Sunday: 70 minutes steady state in the Alden

Sunny, 70s, windy.  Wind SW 5mph with gusts to 15.  Sun sparking on the water.  Really beautiful.

Today the plan was a low intensity steady state session.  I decided to take my Alden out for a spin to get used to rowing it and to figure out what kind of paces are reasonable in a shorter and wider boat.   I went to Lake Whitehall, which is about 5 minutes from my house and is a popular kayaking, fishing, and canoeing spot.  No rowing though.  It works OK, but the longest straight is about 2K and that requires some fancy steering through a couple of narrow spots.  As I found today, it also builds some chop.  It was not an issue in an open water boat, the power boat wakes weren’t either.  They were kind of fun to row over.

The Dual XGPS160 acted up again today.  For the first 15 minutes of the row, the pace was just bouncing all over the place.  Getting stuck for a few seconds, then dropping down to 0:02/500, then returning to normal.  Looking at the view on the map, there were a bunch of zigs and zags as the GPS position got messed up and then locked in again.  For some reason, it started working after about 15 minutes.

The first half of the row was quite enjoyable.  Since the boat turns on a dime, I tried to hug the shoreline more closely than I normally would.   After that, the heaviness of the boat started to get to me.  I learned that the analogy that Concept2 uses to describe drag factor is spot on.  The heaviness on the drive and the faster deceleration were exactly the same.  The only difference is that you don’t have the magical PM making the splits faster for that extra effort.  You just go a bit slower. My best guess is about 0:20/500 slower.  So, the same effort that produces a 2:30 pace in my fluid, produces a 2:50/500 pace in the Alden.

In essence, I will be doing a fair amount of bungee rowing.  This has good and bad aspects to it.  The good is that it slows everything down on the drive so it is easy to focus on blades depth and not missing water at the catch.  The bad is that the load is heavy and I will need to adapt to two very different boat feels.  One thing is clear though.  It is much better than erging, both in terms of the stroke mechanics and also just getting outside and having some great scenery.

By rowing for over an hour, I found two additional issues with the boat.  The first is the seat.  I must have a different butt geometry than what the seat was designed for.  I started noticing some pain at my right sitz bone about halfway through the row and it kept getting worse and worse.  By the time I finished, I could barely support my weight on my right leg, and I was concerned that I might not be able to carry my boat out of the water.  After about 5 minutes, the pain subsided a bit and I could function, but it’s still quite sore today.  I’m going to try to get the exact same seat as what I have in my fluid.  I can sit on that for hours without pain.

The second issue was much more serious, and far more abrupt.  As I was rowing back from the south end of the lake to the launch ramp, about halfway, all of the sudden I heard a big bang off to starboard in the middle of my drive.  I was sure that something had broken, but I wasn’t sure what.  I looked at the rigger and I couldn’t see any damage immediately, so I took a couple of gentle paddle strokes while watching the starboard rigger.  Ah ha!  I saw that the starboard backstay on the rigger had parted right at the oarlock pin.  Every stroke, the rigger was flexing toward the bow.   This picture shows where the backstay broke.

So, now I will try to get some new backstays and get it all fixed up.

Today:  I skipped rowing this morning because I didn’t get to bed until after 1AM last night.  I’m hoping to get a sprint session in on the erg before I fly to Germany tonight on the red eye.  The plan is 4 x (6 x 1′ on / 1′ off) 5′ rest.

 

 

 

Saturday: June CTC – 30R24

Friday:  “Rest Day”.  Flew to San Diego in the morning, and back on the red eye.  I arrived at 7:00AM.  Drove home and slept until around 10:30.

A little after 2, after doing some domestic chores, I found time for an erg session.  The month is passing and I hadn’t made an attempt at the Cross Team Challenge.

Screen Shot 2016-06-18 at 5.55.01 PM.png

I started with a 2K warmup, with 3 bursts of 20 strokes each near my target pace and rate.

Then it was onto the main event.  I felt like an 8K target was about right.  Maybe a bit aggressive since I haven’t been doing much erging and very hard distance work, but I would have felt bad doing less.

I turned out to be doable.  I was a bit fast through the first half, and I needed to bleed off a bit of pace to keep from blowing up in the second.  It was very close to a maximal effort.

I took 721 strokes exactly, according to the painsled file.

Then a 2K cool down

Mission accomplished.

Tomorrow:  Steady State OTW

 

 

Training Principles

It’s a rest day, I’m on a plane heading out to San Diego, and I am bored.  I’m also still trying to workout the best way to train with my work and travel schedule as crazy as it has been.

Any training plan that I devise will need to be quite flexible and simple in order to succeed.  To do that well requires a return to the principles that I have learned about successful training approaches.

Principle #1:  Decide why you are exercising or training.

It is possible to have multiple answers to this question.  In fact, the more reasons you have, the more likely you are incorporate exercise into your life on a permanent basis.  I started exercising as part of an effort to lose weight, and it worked.  I took off 50 pounds.  I also was diagnosed with high blood pressure and my family has a history of cardiac and circulatory disease, and I don’t want to die.  These are the underlying, bedrock reasons why I want to regularly exercise.  But these have been true for my entire adult life, and they were not sufficient to motivate regular exercise until I found a way to connect in to my competitive drive.  Basically, as soon I found the Concept2 online rankings, I wasn’t exercising anymore, I was training.  Specifically, I was training to row faster.  Even more specifically, I was training to row faster than other people.

Rowing on the erg led me to rowing on the water, and that opened up new challenges, both in trying to master the technique and also new ways to compete.  Not only did physical fitness matter, but so did technique, steering, strategy and experience.

Now in addition to objectives to stay healthy, I work to be a better, faster rower than I was the year before and to try to catch up with people that are faster than I am.

Principle #2: Decide how much time you have to train.

Once you do, try to stick to it.  Be brutally honest with yourself up front.  I’ve experienced how demotivating it is to plan more training than I can do and then miss sessions and lose momentum on a training plan.  It would have been much better to set my sights lower.

Principle #3: Set specific a objective and use it to guide your training.

I choose a specific race in the future.  Right now, it is the Cromwell Cup, a 1000m sprint in a few weeks.  After that it will be the Head of the Charles, which is a 5K head race.  You need to know what you are training for to plan out how to train.

Principle #4:  Plan your training before you go to train.

This can be at different levels of specificity.  It might be much easier to decide ahead of time the exact sessions that you will be doing for the next three months, but that only works if you have very good control of your schedule.  If you schedule is erratic, a specific day by day plan won’t work.  In that case, planning a certain mix of training for the week and shuffle it around to make sure that the highest priority sessions get done.  Right now, I am in final prep for a sprint race on July 10th, so my weekly guide is:

  • 2 or 3 sessions that include racing starts
  • 1 session a week with 500m to 1000m intervals at close to race pace
  • 1 session a week with 100m to 500m intervals at faster than race pace
  • as much volume below 2.0mmol/l lactate as I have time for

Principle #5:  Hold yourself accountable.

I find this easiest to do by training publicly.  I try to define my next day’s workout the day before and put it in my blog.  I know that very few people read it, but the fact that I’ve done that makes me feel accountable to either do what I planned or explain why I didn’t.  It is important to make the distinction between accountability and rigidness.  If I don’t follow through with the planned workout, or if I don’t hit my targets, that isn’t a failure.  I just want to be honest with myself about why I changed the plan or wasn’t able to execute it.  That way I can adjust and improve.

Principle #6:  Evaluate performance objectively.

Set quantitative goals and use performance tracking to determine if they are met.  Use past performance to set goals for future workouts.  Try to do the same thing if you are working on technique.  Either use video, or acceleration data to see if changes in technique actually occur.  My ability to remember past performance and discern if I have corrected technique problems is limited at best.

Principle #7: Seek advice, carefully evaluate it and decide if you will use it

There are many people with opinions.  Not all of them are well informed.  It is up to you to figure out what advice is credible and useful and what is not.  Try to establish the quality of the source of advice.  Try to understand the principles on which the advice is based.

Principle #8: Miles make champions

Endurance is critical to all rowing competitions longer than 500m. Building a strong aerobic base is necessary to perform well. The most important factor to building endurance is the volume of training done at low intensities.

Low Intensity Training (LIT) is defined by a blood lactate level below 2.0 mmol/l at the completion of the workout. In order to maximize the effectiveness of endurance training, blood lactate level should be greater than 1.4-1.6mmol/l at the end of the session. Lactate levels should be periodically checked and as fitness improves, LIT intensity should increase to ensure that the end work criteria of 1.4-2.0mmol/l is met.

Endurance training can be continuous or interval based, constant rate or variable rate, as long as it meets the intensity criteria. Up to 1/2 of all endurance training can done as cross training.

Lactate testing is a pain in the ass, does not provide realtime feedback and is pretty much impossible to do in a boat, so an alternative method of gauging intensity is needed. The best alternative for is to use heart monitoring and Rate of Perceived Exertion (RPE) together. By using HR in sessions where lactate is checked, a rough correlation between ending HR and lactate level can be drawn. This can be used as a limit in future workouts until another lactate test is done. The important thing to remember is that this is not a very exact thing. A little too hard or a little too easy will not have much impact on the effectiveness of the workout. The key thing is that easy workouts should be easy.

Principle #9:  If all you do is row slow, you will get good at rowing slow

High Intensity training is necessary to maximize performance at any distance from 100m to a full marathon.  There are different energy systems that are used in maximal efforts.  If these are not specifically trained, performance will suffer.  At least 2 sessions of high intensity training per week.  High Intensity Training (HIT) includes very short intervals, short intervals, long intervals, and hard distance workouts.  The key criteria of these workouts is that lactate levels well above 4.0mmol/l are achieved.  The most convenient way to measure this is to track HR and measure time above lactate threshold.

Principle #10:  You need to be able to pull hard to win races

The ability to generate high peak force on the handle is critical to achieving good speed off the line and to be able to sprint at the finish.  The more force you can exert also means that you can work at lower stroke rates with higher efficiency.  Including some kind of peak power training is useful, especially for sprint racing (1Ks, 2Ks). This can be done on the erg or in the boat with very short intervals with generous rests, or through weight training.  During sprint season, at least one session per week should include peak power training.

Principle #11:  Strength Training is useful, but not critical

This is disputable.  If you have specific strength deficits, then strength training can help with them.  Otherwise, it is mainly useful for muscle group balance and injury prevention.  Right now, I have deprioritized strength training in favor of additional endurance training within the time budget that I have set.  I know that other folks believe this should be a higher training priority.

Principle #12:  Mesocycles work, change it up.

Performance improvements will plateau after 4 to 8 weeks of training with a specific focus.  To combat this plateau, mesocycles can be used to vary the focus of training in blocks.  This can be programmed in a way to build toward a specific event and yield better results than a plan that has the same types of sessions over time.  The final mesocycle before a key event should be focus on maximize performance for the event type.

Principle #13:  The overload principle

Improvement in performance comes from the overload principle. For high intensity workouts, setting targets for pace to be slightly faster than previous results.  For low intensity workouts, increasing duration, and nudging up pace to stay in the desired lactate range over time.  Gradual overload is important.  Big steps in pace are an invitation to disaster.  Big increases in volume can lead to injury as form suffers when you are fatigued.

Principle #14:  Resting is part of training

Rest and recovery are critical to progress.  It is OK to have weeks that over load and under recovery, but these must be followed by weeks where the recovery takes place.  As a general rule taking one day of complete rest per week is vital.  By complete rest, I mean no rowing at all.  The logic behind no rowing is to reduce the risk of repetitive strain injury.  Some kind of other gentle exercise is OK as long as it isn’t long duration and isn’t intense.

Principle #15:  Get a coach

A principle I haven’t been able to follow, but is holding me back.  Real time feedback on performance, especially on technique is critical to improvement.   One Caveat, you and coach need to agree on principles.

Principle #16: Training is easier and more fun if you have training partners.

Thats the thing that I miss most by developing my own training plans.

Principle #17: Lighten up.

If you are reading this, then it is more than likely that you aren’t a professional athlete. We all have jobs, friends and family that are more important than achieving perfection in the execution of our training plans. I am all for having the grit to pound out that last 500 when your legs feel like jelly. I am all for dragging my ass out of bed at 5:15 to get in a training session before work, but if life gets in the way, that’s OK. There are more important things in life than rowing a long skinny boat faster.

Principle #18: Be resilient.

This one goes along with the one before. If sports are not your number one priority, then it is likely that your life will sometime conspire to make you miss your training objectives. When it happens, and it will, just pick yourself up, honestly assess where you fitness is and make a new plan. One of the best things about keeping good training records is that you can look to see how much training you’ve missed and spot trends like regularly missing training volume plans. You can use this to make your plans more realistic or change your priorities or schedule.

Principle #19: Be skeptical.

The world is full of people that are full of crap. They use the internet to spread the fertilizer. There is a lot of good advice out there too. It’s hard to know what is real and what isn’t. Here are my thoughts.
– Research is limited and flawed, but at least multiple people with lots of training in the field have looked at and critiqued it. Its up to you to figure out if it actually applies to your situation.
– Beware of plans for Olympians: I think the most important factor in race performance is total training volume. Elite athletes spend 40 hours a week training. I spend less than 10. That difference is huge and limits the applicability of anything done at an elite level.
– Beware of the “It worked for me” folks. That means you should beware of me too. The critical test is whether or not the advocate can answer the question, “Why does this work?” If it is not based on testable principles or there are not good answers to reasonable questions, then proceed with some caution.
– Beware of facts not in evidence. If someone says that they improved their 2k score by 20 seconds by doing two high intensity erg sessions a week, try to find out what else they are doing. For all you know, they might be running 10 miles every morning. If you just do the erg part, you will probably not see the same results.

Crushed by the lactate wave. 750m intervals

Weather: sunny, warm mid-70s, basically no wind. A great day for rowing. 

Pity it was such a shitty workout. 

Plan:

  • 8×750 / 4′ rest
  • Rate: 28-32
  • Pace: 2:00
  • Standing starts
  • Paddle in the rests

I am feeling the effects of a big increase in Volume. I got my boat back last week and I’ve rowed everyday since last Friday. I’ve also done longer sessions this week. Last night, I got enough sleep, but I woke up feeling very sore and lethargic. I also had stomach issues which forced me stop for an unscheduled pit stop on my way to the boathouse. 

By the time I got on the water, it was nearly 7am, and I had less than an hour for the workout. I did a quick warmup and then attempted to start the first interval. I got 5 strokes in and noticed that I hadn’t pushed start on CrewNerd. The second attempt at the start actually worked and off I went. I took a little too long to settle down to a realistic pace, and I felt the familiar “Lactate Wave”. Nausea, feeling like I’m drowning. This is a feeling I hate, but I need to get used to in order to well in sprint races. It’s kind of the whole point of this workout. 

The problem is that I was not mentally prepared for what this workout demanded. I made it through the wave in the first interval by slowing down. The second interval, I powered through it and was happy that I hit the target pace, even while steering to the bridge. This one really hurt after I finished. I nearly puked, but by the end of the rest I thought I was better. 

Twenty strokes into the next interval, I discovered that I wasn’t. I bailed out the interval approaching the bridge, and then slowly picked back up to a reasonable pace for about the last 400m. I was pretty annoyed with myself. 

I paddled through the s-curve during the rest and decided to hold the rate a bit lower during the next interval. The result was a slower split and a more manageable wave. 

I quit on the next interval and frankly, I’m not even sure why. It was after about 20 strokes, and this time I picked back up pretty quickly and pushed through the rest of the piece. This was not going well. 

I was running out of time and so I decided to make the next one my last. No quitting allowed on this one. I managed the wave and finished reasonably well. 

I rowed feet out back to the dock. I have to come back and do this workout again soon.

Tomorrow: “rest day”. I’m flying to sandiego in the morning and back on the redeye. Some rest day. 

Wednesday: Steady State Rate Ladders

Weather: Sunny, 70F, light shifty wind from the WNW about 2-4 mph.  Wind was not really a factor, but slowed me down at times.

Plan:

  • 6′ Rate Ladders
  • 3′ @ 17 / 2′ @ 19 / 1′ @ 21
  • 1′ rests when I turned at the ends of the river.
  • Technique Notes:  Keep the drive smooth.  Get the blades off the water.

Screen Shot 2016-06-15 at 9.22.44 AM

Notice the purple box?  If you look over to the right hand side at the speed scale, it indicates that I was going 4600 km/h.  Pretty nice acceleration, eh?

What actually happened was the Dual XGPS160 unit and it took me a little while to notice.  The interesting thing is that the pace and distance seemed to update for a while after the point where the straight line started.  I thought it was only about 30 seconds or so where I saw the pace and distance frozen before I stopped and cycled power on the unit, but the data is missing for nearly 9 minutes.  Some weird s**t going on here.

Cycling the power made everything happy again.

Today was a day of mishaps.  On my last trip down the river,  Was trying to squeeze in the end of a ladder and I pushed it too far.  There is a cable across the river with big orange floats (about 18″ in diameter) strung on it.  I put on the brakes, and tried to turn, but managed to get my bow and starboard oar blade under the cable between two floats, and my boat basically parallel to the float line.  What ensued was an ungainly display of backing and forthing and turning and wobbling as I tried to get my bow extracted, my boat turned around and get myself clear.  It was an ugly demonstration of what not to do in a boat.

After that, I finished the journey up river and was approaching the dock.  There are a few challenges to deal with.  First, there was a bit of cross wind.  No big deal.  Second, there is an underwater propeller under one side of the dock that is artificially creating a current to try to keep area by the dock clear of weeds.  Also no big deal if you approach the other side of the dock.  Third, is the weeds themselves.  They are floating in great clumps right now.  This was the cause of my downfall today.  I was aiming to put my bow about a foot away from the side of the dock, so I would come in on the port side of the boat.  But when I was about 6 feet from the dock, my port oar caught a great hunk of weed, and turned my bow to the port side.

With a small bump, I hit the end of the dock.  No big deal, right.  The bow ball is there, right?  Well, on this specific dock, there is a 4″ wide gap between the board along the side of the dock and the one on the end of the dock, and my bow hit that gap with extraordinary precision, and the bow became wedged between the two bits of wood.  I had to back the boat with a fair amount of pressure to get it free, and it took a couple of strokes to do it.

Between those strokes, I was processing what the hell I would do if I couldn’t get it free.  I guess, jump out and swim.  That would have been pretty damn humiliating!  I’m glad it didn’t come to that.  There was no damage to the boat.  In the future, I will approach the dock with less speed and more paranoia.

Tomorrow:  8 x 750 / 4′ rest.

 

Tuesday: Starting to work on Starts

Weather:  Basically like yesterday.  Sunny, cool and blustery.  Generally WNW, 5 mph with gusts to 15 mph.

Plan:

  • Rojabo style warmup to the moody street dam
  • Do as many starts as I can stand
  • 15 strokes each start, 10 stroke paddle, then stop the boat, reset and do it again
  • In each start work on:
    • Get set comfortably at the catch.
    • Do NOT go to full compression, stop when it feels like my heels are beginning to lift.  The key is to be rock solid at the start of the first stroke.
    • First stroke:  Smooth, powerful acceleration, very early finish, get the blades way off the water, barely feather.
    • Second Stroke:  get back to 1/2 slide fast!  get the blades in, keep it smooth, finish early, get the blades clear
    • Third through fifth:  keep taking short strokes and focus on balance and finishes
    • fifth through tenth: extend out to full slide.  Keep stroke rate up above 38, but keep recovery smooth.
    • 10 to 15:  full pressure, good strokes
  • Long cool down focusing on technique

Here is the whole session in google earth.  I paddled to the lap02 flag, then did the Rojabo warmup.  That took me to the end of the basin in Waltham.  Then I turned and did 14 starts going up river and generally with a cross/tail wind.  That took me back to the beginning, I had a drink, turned again, and did another 14 starts going back down river, now with a bit of a head wind.  A few of them, especially #’s 22 to 25 were definitely impacted by a reasonable strong headwind at the time.

Screen Shot 2016-06-14 at 2.00.23 PM

Here’s the whole session as interpreted by Rowsandall

myimage (17)

This is time based, so it gives you a better picture of the gap between intervals.  There is something fishy about the pace display.  The graph from google earth is in km/h.  Here is a closer view of the speed.

Screen Shot 2016-06-14 at 2.20.57 PM

The top speed is 18.7 km/h.  This is a foreign unit to me, so here’s the translation

  • 15 km/h = 2:00.0/500
  • 17 km/h = 1:45.9/500
  • 19 km/h = 1:34.7/500

This intrigued me enough that I exported the CSV file from crewnerd and plotted it in Excel.

That matches Google earth.

Next time, I will set it up as a predefined workout in Crewnerd.  15 strokes on and about 1:30 rest would be about the same thing.  I’ll have to pause it sometimes to get to a fortuitous starting point, but it should workout OK.

Other than the interesting pace discrepancies, it was a useful and interesting workout.  The key really is the first stroke.  Being a little conservative and finishing clean is the biggest thing.  Once the boat starts to build a little momentum, it gets easier.

I’ve registered for the Cromwell Cup.  This is a 1km sprint race on July 10th.  So, that should provide some motivation to do some more start practices.

I also had a useful live demonstration of the value of magik oarlocks.  Right now, one of the tension bands, the one on my port oarlock, is busted.  So that oarlock acts just like a normal C2 oarlock.  The tension band on the starboard oarlock is intact, so the little lever applies pressure to the stern side of the oar.

Screen Shot 2016-06-14 at 2.35.06 PM

In normal rowing, I can detected no difference between port and starboard, but sitting at the catch with blades buried, I sure could.  With the wind today, there was a bit of chop, and I could feel my port oar rattling around at the catch, my starboard oar was just solid.  No movement at all.  I don’t know if it was coincidence, or self fulfilling prophesy, but most of the problems that I had with imperfect first strokes were on the port side.

I enjoyed the cool down.  I did two repetitions of 500m SBR, 500m of alternating SBR and normal, and 500m of slow roll ups.  That took me back to the cut.  From there it was just a paddle back to the dock.

Tomorrow:  Another session of easy rate ladders.  HR cap at 155.

Monday: Easy Rate Ladders

Weather:  Sunny, upper 50s, Windy!  Sustained winds around 10mph, with gusts to 20.  Shifting around between the west and the north.

Rowing on  the upper charles from newton down to Waltham.  In my wonderful Fluid.

Plan:

  • Rate Ladders (3’/2’/1′)
  • Rate: 17 / 19 / 21
  • Pace:  Completely useless with the shifty wind
  • Technique:  Work on getting way out at the catch and slowly squaring the oars at the catch.

I used Crewnerd with the Dual Skypro XGPS160

Screen Shot 2016-06-13 at 11.47.09 AM.png

This unit provides a 10Hz update rate for GPS information to the iPhone over bluetooth.  This is 10x faster than the internal GPS of the iPhone.  This is a good thing because pace changes should be reflected more quickly and accurately in CrewNerd.  If you are getting updates that quickly, you can turn down the smoothing from ~100m to ~20m and the annoying lag is a lot better and with the fast update rate, the pace does not hunt around.  When it works it works great, unfortunately I have never been able to complete an entire workout without the unit hanging up.  When that happens, the pace and distance on Crewnerd stop updating.  It happened to me today.  You can see it in the map below where the course goes from yellow to red.

The updates actually stopped about 1km before that, at the little blue flag.  Here’s a zoom in.

The updates stopped coming out of the s-curve.  It seemed like the display was live for at least another 2 minutes, and then froze, about 100m before the “lap001” flag.

I experimented to try to figure out what was going on.  I quit crewnerd and restarted it.  It was still not updating pace and distance.  I started up the XGPS utility app.  It took a while to open, and then finally failed, and crashed.  Next, I cycled power on the XGPS unit, and that seemed to do the trick.  But I am not sure that the iphone was actually using the XGPS anymore because the pace was madly misbehaving.  It was misbehaving just like it does when you don’t use enough smoothing and the internal GPS.

Anyway, I am not sure if it is the worth the hassle to use the XGPS.  I like the crisper pace display, but it really pisses me off when technology does not work reliably.  I’ll be glad when I get my impeller back.

So, back to the workout.  My pace was terrible and all over the place because of the wind.  I focused on trying to hit my rates and keep my HR below 155.  I also focused on the technique notes.  Even though it was windy, I really enjoyed the session.

The first plots are for the bulk of the session, up to the hang.  The second is for the last 2 minutes of the last ladder and the paddle back to the dock.  Looks like I did 12 complete 6′ ladders.

Tomorrow:  Time to start working on starts!  The plan will be to do a long warmup (Rojabo style) to the Moody Street dam, and then do starts, lots of them.  Basically 20 strokes from a standing start, paddle 20 strokes, stop the boat, repeat.  Focus is on cleanly building speed and hitting stroke rates in the mid 30s during the second 10 strokes.

 

 

Sunday: 4 x 20′ / 1′ rest L4 on the erg

Plan:

  • 4 x 20′ / 1′ rest
  • Power: 10W x stroke rate
  • Heart rate cap at 155

It should have been easier.  I set myself up on the porch.  It was beautiful outside.  Windy and around 70F.

2016-06-12 13.42.06

It should have been a really easy row, but I started feeling the effects very soon into it.  I started conservatively at 18spm and 180W.  My HR climbed steadily through the first 20 minutes and was well into UT1 by the end of that piece.  By the end of the second, I had pushed past the HR cap, so I retreated to a L4 format sequence

  • 4′ at 16 (160W)
  • 3′ at 17 (170W)
  • 2′ at 18 (180W)
  • 1′ at 19 (190W)

Even with this downshift, I still spent a lot of time above my HR cap.  I think I need to do some lactate testing to see where I am these days.

Tomorrow:  Back in Newton in my own boat!  Hurray!  Steady state rate ladders 3/2/1 format at 17/19/21.  HR cap at 155.

 

A whole boat load of 1′ intervals

Cloudy, calm, upper 50s.  A little bit of a wind from the south picked up while I was rowing.  About 3-4 mph by the tie we finished.

I was out in Worcester on Lake Quinsigamond with my clubmates today.  We had 10 of us.  We boated 2 quads and two singles.  I had cartopped my wonderful, repaired fluid.

Last night I stopped at the hardware store on the way home and picked up some silicone sealant.  I repaired the small leak behind the fin in the parking lot, and then continued my drive home.  Today, the repair was set and there was no water in the stern when I finished.  Tick that item off the list.

The plan was for 1′ intervals.

  • 6 x 1′ on / 1′ off
  • 4 sets with 5′ rest or so between sets
  • Target pace: 2:00
  • Target rate: 30 spm
  • Technique Objective:  Smooth recovery, good catches, smooth acceleration, early finish.

We were on the water around 7:30 and the lake was beautifully flat.  I did about 2000m of warming up going down lake and then set off on my first set.  In the fourth interval I was waked by a waterskiing boat, but nothing too serious, it just made me miss a coulpe strokes.  The fifth interval took me all the way down to the south end of the lake, so I had to spin and come back north to finish the first set.  I then spun again and hung around until every one was down in the cove and ready to head north.

By the time I finished the 5th interval of the second set, I had just passed the narrows going north.  During the rest between the 5th and 6th interval, I was passed at close range by another waterskiing boat.  I paused the timer during the rest to let the wake pass me before I started the sixth, but I was working from a standing start and the water was still pretty messed up.

I was feeling some fatigue by this point and I paddled the 4′ rest pretty slowly continuing north.  The first interval of the 3rd set brought me under the route 9 bridge.  The next 5 intervals brought be all the way up to the Donahue Rowing Center.  I finished my last interval in front of their docks with a number of people standing there watching the old guy gasping past at 30 spm.  I tried to look as debonair as possible.

I paddle up to the north cove of the lake and spun around.  After we had reassembled, I took off back home.  There was another single that took off when I did, but he didn’t take the bait and turned into the DRC docks.  My legs were pretty much done, so I let the rate sag a bit.  I was waked again in the 4th interval, but I tried to make a good finish in the last 2.  This brought me just past our docks, so I spun and went back in without much of a cool down.  I crawled out of the boat.  34 minutes in the TR zone.

It would be nice if I was faster, but it I felt more comfortable at r30 than I expected.  It would also be nice if I had my speedcoach.  The pace lag on short intervals is awful on CrewNerd.  If I don’t have my impeller mounted by next weekend, I might risk using the Dual GPS dongle to make it a bit better.

Tomorrow:  4 x 20’/1′ rest on the erg, nice and easy.

Friday: 8K steady state in the Miracle Shell

Weather:  Broken clouds, occasional drizzle, windy.  WSW 5-10 mph with higher gusts.

Back in the saddle!  While I was in Phoenix, the good people from Fluidesign dropped off my boat.  I am massively impressed with the results.

Here’s the before picture:

And here are the after pictures:

The finish is beautiful, and there are only the the slightest hint of a ripple where the carbon had been creased and torn.

On the water, the boat felt just like before.  Stiff and responsive.  It set well and had been rerigged perfectly.  It tracked perfectly.  I am amazed at the repair.

By the time I had gotten it all unpacked and all the gadgets mounted, I was short on time, so I did a quick 8K steady session.  I wanted to take it easy and make sure that I felt confident in the boat before I did anything too intense.  I loved being back in my boat!  For the same effort, I feel like I am about 5 seconds faster on pace.  A little tough to tell because of the breeze this morning, but the speedcoach seemed much more willing to spend time below 2:30 pace than in the peinert.

Of course there are a few nits that I need to take care of on the boat.

  1.  They reset the fin when they repainted the boat.  In doing that they did not notice the damage behind the fin from a close encounter with the sunken log (Trees and this boat do not get along!)  During my row, I shipped a little water in the stern.  I just need a dab of silicon over the area and it will be fine.
  2. When they refinished the boat, they forgot to remount my impeller.  I didn;t even notice this until I was rowing and saw the pace display on the speedcoach stubbornly staying blank.  I felt under the boat to see if the impeller was fouled with weeds and discovered that it wasn’t there!  I’ve asked them to send it back to me so I can get it put back on.
  3. I noticed that an elastic bands on one of the Magik oarlocks had snapped.  This band opens the oarlock when the latch is disengaged, so it is not critical, but I’d like to fix it.

All minor, and easily fixed.

Tomorrow:  Out to Worcester.  Time for a bit  more intensity.  I’m thinking of doing a  4 x (6 x 1′ on / 1′ off) 4′ rest at r30.
