Back at base building. The mission today was to hold exactly 185W and measure lactate after 80 work minutes. I want to have a consistent training power that will yield 2.0 mmol/ml lactate readings at the end of a session.
It appears that lactate levels over time during endurance training can be different from person to person. What I have seen is that mine tend to stay at a reasonable constant level below 2.0mmol/ml for about 60 minutes, and then as I get fatigued, they start to rise. My Rate of Perceived Exertion (RPE) follows. I start to breath more heavily, and it feels like a lot more work in that last 20 minutes.
So, I aimed for 185W and I got 186W. In terms of my HR limits, it was right on. I measured lactate at the end…2.7mmol/ml. So, I need to back off the power, just a little bit.
I plan to aim at 180W for the next session and see what that gets me.
I’m at the airport now heading for LA. We’ll see if I can find a crossfit gym to drop into tomorrow, or else I will crosstrain in the fitness center.
