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)

Here is the rate data

Tabular comparison of impeller and GPS

2:26.2 vs 2:22.9 –> 3.3 – down stream
2:28.2 vs 2:24.6 –> 3.6 – up stream
2:28.4 vs 2:25.4 –> 3.0 – down stream
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.
