Tuesday: 75′ steady state OTW

Weather:  warm, humid.  A bit misty.  A light, shifty wind always seemed to be a headwind.

Plan:

  • 4 x ~3K + 1K wu and 1k cd
  • 1′ rest
  • first 2 segments at r18
  • last 2 segments at r20
  • HR cap at 155

Another session where things just didn’t seem to go very well.  I tried to ignore  pace and focus on my posture and technique, but the pace that I was ignoring just seemed to get slower and slower.

Tomorrow:  Threshold session in a 2x with Joe out at Lake Quinsigamond.  The goal will be to practice turns under pressure and get our technique more together at r26.

My idea is a few sets of figure eights.  If we start at the beach and finish at the beach, they will be 2.5km long.  If we start at the island, they will be 2k long.  I’m thinking a 4x2k might be a good choice.

Saturday: CRI Fall Challenge

Weather:  Bright sunshine, temperature started in the low sixties, but warmed up.  A Southernly breeze kicked up right when we were starting our race.  This was mostly a cross headwind.

I was rowing stroke, Joe was in the bow.  This is a 5km head race that shares about half of it’s course with the Head of the Charles.  It starts upriver from the Weeks Bridge, and finishes at the CRI boathouse.

It’s not a big race.  There was one event with 2 boats in it before us, the Men’s Open 2x, then us, the Men’s Masters 2x.  There were 5 boats in our event.  And we were starting 5th.  Behind us were the Men’s Junior 2x and then the Men’s Masters 1x.

The race starts at the right and proceeds to the left.  The race plan was broken into 4 parts.

1.  Anderson to Eliot: 1.2km
– Straight shot from  the bridge to the turn for about 600m, then a broad sweeping turn for another 600m
– The hard part is that the turn gets much tighter right at the end so you have to be ready to lean hard on starboard to make the middle arch.
– The race plan is to hit the first 500 pretty hard at about a r28, and then focus on trying to row clean at r26 through the turn.
2.  Eliot to Arsenal: 1.8km
– This is the guts of the race.  It’s pretty straight and there not much you need to do but stay reasonably close to the Cambridge side.
– In this section, we should stick around a r26 and work on keeping it together.
– It is probably a good idea to call some 10s in this section to focus on whatever parts of the stroke are getting wobbly.
3.  Arsenal to N Beacon: 1.2km
-Digging deep at this point.
– I am hoping that we will have managed our pace well enough over the prior section that I can lift the rate to 28 in this section.
4.  N. Beacon to the Finish: 400m (more or less depending on where they set the line.
– I plan to crank the rate up to 30 or higher while we are under  the bridge.
– Coming out of the bridge, with the rate still at 30, you need to call for tons of port pressure to hold  the line.
It didn’t play exactly to plan, but it was pretty close.  We were slower than either of us were hoping we would be.  And we finished last in our event.

So, we finished 53 seconds behind the guys who finished fourth.  So, over a 5k course, that means that we need to improve our average pace by just over 5 seconds.  We did this race at a 2:23 pace.  Here are the splits

|06700|00500|02:15|02:15.0| 27.8  | 161  |08.0| tail wind

|07200|00500|02:14|02:14.0| 26.2  | 169  |08.5| tail wind

|07700|00498|02:27|02:27.6| 26.6  | 173  |07.6|head wind

|08198|00500|02:24|02:24.0| 27.6  | 174  |07.6|cross head for the rest of the way

|08698|00500|02:25|02:25.0| 27.0  | 176  |07.7|

|09198|00500|02:26|02:26.0| 27.3  | 176  |07.5|

|09698|00502|02:28|02:27.4| 27.1  | 177  |07.5|

|10200|00497|02:23|02:23.9| 28.3  | 177  |07.4|

|10697|00503|02:28|02:27.1| 27.8  | 179  |07.3|

|11200|00499|02:21|02:21.3| 29.5  | 181  |07.2|

Reviewing it, it is worthwhile to break it down into parts to try to improve.

1.  Rate:  The overall rate average for the race was a 27.5.  This is higher than it should have been, and that’s entirely on me.  I was over excited and I didn’t do a good job holding 26 through the guts of the course.  The higher rate made it tougher for Joe to stay in sync, especially with all the steering he had to do.  This is just a matter of having better discipline.

2.  Steering:  I am frankly quite impressed with the line that Joe steered.  He has never rowed this river before, and in comparison with the two boats behind us, it was clear that he was steering better and putting distance between us and them at a couple crucial spots in the race.  There were a few spots in the race where we needed to turn sharply enough to hammer our boat speed.  The first of these was right out of the Anderson Bridge, where the river turns toward Cambridge and the buoy line snuck up on us.  The second was the turn into the long straight section by Soldier field.  The river bends toward Cambridge and we swung out into the buoy line.  The final time was coming out of the N. Beacon Street Bridge, right before the finish line.  The turn is quite sharp and we needed really hammer the port strokes to stay on the course.  As I watched some races after ours, it seems like that last turn is a tough on, no matter how perfect your line is.

I think it will be critical for us to get some runs on the HOCR course so that Joe has a chance to learn the land marks and rehearse the turns.

3.  Technique:  Here’s the area where we can do  the most to improve.  All of our practice together has been on Quinsigamond and so, we have just gotten to the point where we can get synchronized and clean on the gloriously long straight sections of the lake.  On a twisty turny river, where we are always pulling harder on Port or Starboard, and Joe has to have his head on a swivel to find the line, we were no where near clean.  I know that my finishes were sloppy, and I was typically dragging at least one blade on recovery.  Joe said essentially the same thing, that trying to steer and maintain the rate really made it hard for him to “get in a groove”.  So what do we do?  A couple of things.  First, I keep the rate at 26, don’t get all fancy with higher rate for now.  Focus on getting good at that rate.  Second, practice full pressure turns.  I took a look at the Eliot turn, and superimposed it on a same scale map of Quinsigamond.   If we turn at full pressure around the big island, and then loop around the small island to the east to go back up lake, we get something that is very much like 2 or 3 Eliot turns.  I think a couple of reps of that during each workout will give us enough time turning under pressure that we can hold our technique better.

4.  Fitness:  Joe is still rehabbing from a surgical repair for a torn biceps tendon, and I haven’t had as much time or focus as I did last year.  So, I think we have to be realistic.  We have 34 days from now to the HOCR.  Maintaining as full of a training plan as possible will be helpful, but is unlikely to yield massive improvements.  I’m going to stick with my predefined plan.

5.  Effort:  As near as I can tell, we both put everything we had into the race.  Here’s the Pace and Rate plots, with my HR.  So, the last 5 minutes of the race was anaerobic.  I felt spent at the end, but pretty much OK.  But at the dock, I experienced something new.  I had a massive coughing jag, and nearly threw up.  It didn’t feel exactly like an erg cough, but it was a bit disconcerting.  But, I certainly felt like I put everything I had into the race.

|00020|06684|53:33|04:00.4| 18.8 | 127 |06.6|warmup
|06700|04999|23:51|02:23.1| 27.5 | 174 |07.6|race
|11699|00493|07:13|07:19.1| 20.5 | 133 |03.3|back to dock

The race was a massively useful learning experience.  The good news is that there is a lot of stuff to work on that will make us significantly faster.  The bad news is that we have a lot of ground to make up.

Later today, I will do a normal endurance session.  Tomorrow morning, back to the lake for a session with Joe.

 

Tuesday: 74 minutes of Steady State

Weather:  Awesome.  Clear, cool.  A very light breeze from SW, barely noticeable until the last segment when it built enough to slow me down.

Plan:

  • Recover from yesterday’s intense session
  • >70′ steady state
  • rate: 20 spm
  • pace: ~2:30
  • HR cap: < 155

I had trouble getting organized this morning.  I was late leaving the house.  I needed to stop on the way to the boathouse to use the bathroom.  There was goose poop all over the dock (luckily I am now carrying a broom in my mobile boathouse).  And I managed to forgot my “Bite Guards” in my duffel and didn’t realize it until I was twenty strokes from the dock.  I wanted to row with them because I had some raw spots from the double yesterday that I didn’t want to irritate further.  Oh well.

I am also still struggling with the speedcoach.  I need to recalibrate the pace, and the HR pickup antenna has come loose from the bottom of the seat deck.  It’s been a problem finding time to do this kind of routine stuff because I am pressed for time in the mornings during the week and skipping off to the cape on weekends.  Oh well, I am more and more happy with the the way that RIM is working.  The pace seems much more responsive than CrewNerd in the boat, and the live acceleration graph definitely keeps me focused on form later in each session.  You can definitely tell from it when you are shortening the stroke, or rushing the catch and a myriad of other issues.

Today’s workout was almost entirely uneventful.  I would like to be faster, but I have to be realistic about making progress when I have other priorities that reduce the time I have to train.

First Interval, for some reason HR data wasn’t working in RIM

Put all the reps together and the pace is 2:27.9.  Not bad for the HR I guess.

Now I am on a plane over Oklahoma, on my way to LA.  I have customer meetings tomorrow and Thursday morning.  My plan is to drop in on Crossfit Anaerobic in Newport Beach and use an erg.  My workout plan for  the week is a bit disrupted, and I have my first head race this weekend.

The plan was

  • Monday:  rest
  • Tuesday: Threshold 4×2500
  • Wednesday: Steady State
  • Thursday: Short rest intervals 4 x (3′ on / 1′ paddle) 2′ rest
  • Friday: Warmup Only
  • Saturday: CRI Fall Classic

The new plan is

  • Monday:  Threshold – 5.5km hard on Quinsig
  • Tuesday: 75′ steady state
  • Wednesday: Short Rest Intervals (on the erg)
  • Thursday: Steady State 4 x 20′ (on the erg)
  • Friday: Warmup only
  • Saturday: Race Day!

I’m not tapering for this race, I think it’s more important to keep working on endurance for the races later in the schedule.

 

Wednesday: 14K Steady State

Weather:  Intermittent light rain.  Overcast.  Light wind from the east ~2mph.

Plan:

  • steady state
  • 4x the length of the river
  • r20.
  • HR cap at 155

Sometime when it rains, rowing can be a magical experience.  The rain flattens out the water, and the it muffles all the noises.  You feel like you are gliding effortlessly along.

Today was not that day.

Today, every stroke felt sluggish.  The splits were slow and the it seemed like the boat was 50 pounds heavier than it used to be.  The 2mph headwind made it feel like I was rowing up a long slow hill.  And when I turned around, it seemed like the wind just disappeared.

But, I went out and I did the work.  Good for me!

Very high HR for a 2:30 pace.  Oh well.

Tomorrow:  Short rest intervals.  Plan calls for…5 x 20@32/10 off / 5 x 20@34/15 off / 5 x 20@36/20 off, 8′ between sets

I don’t think I want to do that.  I think I will substitute a 4 x (8 x (1′ on / 30″ off) ) 4′ rest

Thursday: 4 x (5 x 2′ / 1′ rest ) 4′ rest

Weather: light wind from the west, this slowed down the second and fourth sets a bit.

Plan:

  • 4 sets of 5 x 2′ / 1′ rest
  • each set would cover the length of the river.
  • 4′ rest between sets
  • pace: < 2:15
  • rate: 26

Even allowing for the speecoach miscalibration, this was about a second slower than I would have liked.  But it was darn good training.

 

 

Wednesday: Steady State (and more accuracy fun)

Weather:  Yawn…Another perfect day.

Plan:

  • 4 x ~14min
  • rate 20
  • pace target < 2:30
  • HR cap < 155

 

So, here is the pace plotted for GPS (on the left) and speedcoach (on the right)

2:32.6 vs 2:29.2 –> 3.4 – up stream

current effect ~ 3.5 – 3.15 (avg of 2 ups – 2 downs) = 0.35

So, the downstream pieces GPS will read .2 faster than impeller, up stream .2 slower
Average difference between speedcoach and GPS –> 3.4 seconds (impeller is slower)

Yesterday the difference was around 2.5 seconds difference.  I think I need to recalibrate my speedcoach.

Tomorrow:  My first outing doing short rest intervals in this mesocycle.

4 x (5 x 2′ on / 30″ paddle) / 2′ rest

The 2′ on is supposed to be at head race pace.  I’ll target 2:15.

Tuesday: 4 x 2500 / 5′ rest

Weather:  Amazing!  Cool and dry, very little wind.  I launched just after 6:30.

Screen Shot 2016-08-30 at 1.49.03 PM

Plan:

  • 4 x 2500
  • 5′ active rests
  • rate target: 26
  • pace target: 2:15

I am pretty darn happy with this workout.  I would have been happier if it was faster, but I executed this workout to the best of my ability.  No theatrics, no bailing out.

There was one weird thing with today’s workout.  I was seeing a persistent difference in pace between the speedcoach and the GPS.  Now, over a short span, I don’t expect them to read the same, but for basically the whole row downriver, I was seeing the GPS based numbers giving a pace 2 to 5 seconds faster than the impeller.  Must be flow, you might be thinking.  At least that was what I was thinking, but right now, there is essentially no flow.  The water level is so low that basically nothing is going over the dam.  And when I saw the same thing going up river, I decided that something was fishy with the speedcoach impeller.  Either the cal was off, or there was something fouling the impeller.

Here is a comparison of the paces for the four pieces.

GPS — Imp –> Delta
2:12.0 — 2:14.6 –> 2.6
2:14.9 — 2:17.4 –> 2.5
2:16.1 — 2:18.7 –> 2.6
2:16.7 — 2:19.5 –> 2.8

I saw nothing on the impeller when I pulled the boat, so I will do the comparison again tomorrow and update the cal if there is still a difference.

Here’s the (slow) speedcoach data.

For comparison, here are the first 3 intervals based on TCX data from RIM.  The pace data is a lot noisier, but the eyeball average is about 3 seconds faster.  I had a glitch with the phone and the data for the 4th interval ended up in a different file.

Here’s the TCX data for the fourth interval.

Tomorrow:  75′ Steady State, 20 spm, HR cap at 155.

Monday: Steady State Rate Ladders

Weather: broken overcast.  Warm and humid.  Light wind from the W.  This was a headwind going up river, but not much of a factor, maybe 4 seconds on pace.

Screen Shot 2016-08-29 at 11.31.23 AM

Plan:

  • Rate ladders
    • 4′ at 18
    • 3′ at 20
    • 2′ at 22
    • 1′ at 24
  • Pace targets:  2:30 for r18, and faster with higher rate, maybe 3 sec for each step.
  • HR:  Cap at 155

Screen Shot 2016-08-29 at 11.32.16 AM.png

Tabulated pace and rate data from the Speedcoach.  This let’s me break it down by rate.  I blocked the 1 minute chunks around each turn around to get a better estimate of actual pace.  I finished with the ladders at 1:01, and then rowed with square blades back to the dock as my cool down.

So, a bit slower for the r18 than I would have liked.  About 3 seconds faster for r20.  3.8 seconds going from r20 to r22 and 6.4 seconds faster going from R22 to R24!  Interesting to see the HR following the rates too.

Here’s the view of the workout from the TCX data collected by RIM and process by rowsandall.com

Tomorrow:  Long Intervals – 4 x 2500 / 5′ rest.  rate target r26.

 

 

Thursday: 14K steady state (r18/r20)

Weather:  Sunny, beautiful.  light wind, building from the west.  This was a head wind going up river.

Screen Shot 2016-08-25 at 11.58.05 AM

Plan:

  • 70 minutes of steady state
  • r20
  • pace target: around 2:30
  • HR cap: 155

A very nice row.  No complaints.  Getting way out for the catch sure makes a big difference to boat speed.

Tonight my wife and I are heading back to the cape.  If the weather is nice, I’ll do an open water row tomorrow morning.  If not, I’ll go for a bike ride.

 

Tuesday: Speedcoach Calibration and 14K of steady state

Weather:  Crystal clear.  Very Sunny.  Cool and breezy.  Wind NW 2 to 5 mph.

The main objective today was to get the new impeller mounted for my speedcoach.  Once it was mounted, it needed to be calibrated.  So, I popped it in the water and headed out.  I usually row in the early morning, but today, I had some things to do at home in the morning.  So, I launched around 1:00 in the afternoon.  Since it was such a nice day there were a lot of kayaks, pedal boats, canoes and various other water craft out enjoying the day as well.  Even though I was looking around constantly, I still had to back down hard a few times when a boat zigged instead of zagging, or I missed them in my scans.  Despite this, it was a glorious day to be out rowing.

Plan:

  • Do 2x 1000m at r24 in opposite directions to calibrate the speedcoach.
  • 80 minutes of steady state

Leaving the dock, I started RIM and reset the speedcoach.  After I warmed up and got to the start of the straight part of the river, I realized that I really should be using Crewnerd for a autostart 1000m piece for speedcoach cal.  So, I flipped over and started up crewnerd, losing the first 1200m of rowing.

The 1000s went fine.  The first one was with the light wind and was done at an average pace of 2:11.4.  The second was upwind and the pace was 2:13.3.  I was winded but I didn’t push them all that hard.  After that, I did the river twice from the start to the moody street dam.  At first I was feeling like I was really struggling to hit any reasonable split.  But eventually, I started to row a bit better and sped up.  The main difference was focusing on getting way into compression at the catch.

Tomorrow:  Some more steady state.  80′ at r20.
