I felt tired at 5:15 so I rolled over and slept 2 more hours.  I’m glad I did.

I headed to the gym at lunch and sat down on the new erg.  And my HR strap didn’t link up to either the PM5 or the phone.  I popped out the battery and it was wet.  Uh Oh.  I put in a new battery.  Still no life. I think the seal must have gone and sweat has gotten into it.

I pulled out my old wahoo tickr and put a new battery in this one.  I had stopped using this one because it seemed to have a problem following fast HR changes, like you see in interval sessions (like today’s workout).  This one linked up right away, and I got going with the workout using painsled.

The plan:

• 15 x 3′ / 1′ rests
• Pace: 1:54
• Rate: 26
• Technique: knees together, limit layback
• HR limit: none

So the sensor still has issues.  Glad it wasn’t my imagination.

So, targets met.  Tired now.

Tomorrow:  80 minutes of endurance training.  20 minutes treadmill, 3 x 20′ on the erg.
