Today I ignored lesson 1 for steady state sessions. If it is supposed to be a UT2 or UT1 session, it is not supposed to feel like hard work. If it does, you should back down, reduce the intensity, or even just stop and take a rest day.
For science (or rather for my curiosity as my method lacks scientific rigor), I pushed on.
A lot of things were different today, compared to the steady state sessions that I measured lactate on so far:
- I didn’t sleep well. I woke up from a dream which I could remember quite vividly, which doesn’t happen very often. It was 3AM. Between 3AM and 6AM I was turning in bed, not sleeping well.
- I cycled to work. Made a point of cycling very lightly, “to get yesterday’s heavy session out of my system”.
- I had a big cold salad for lunch, then nothing for the entire afternoon, and for dinner I decided to add an omelet to my usual light dinner.
- The weather has changed from nice, cold and dry to 10 degrees C, rainy and humid.
- It is not November any more.
I did a 3×20 min tonight with a lactate measurement after the last 20 minute interval.
I warmed up for 5 minutes.
First interval didn’t feel too bad. I slowly ramped up the power for the first 10 minutes and ended up doing a 190W on average.
I rowed the second interval with an eye on the clock. It seemed endless. I knew I was working harder than I want to work in steady state sessions, but after 10 minutes funnily the pace started to drift to 210W and I had to consciously keep it down. Still, my breathing and the feeling in my legs told me I was working too hard.
The third interval was hard. The kind of annoying steady state “hard”. It just took too much mental effort to hold the pace. I did some stroke rate changes in the first 10 minutes just to keep the focus. Took a lactate measurement immediately after the interval:
Feeling confirmed. I was actually very happy about this result. It gives me more confidence in lactate measurement as a method to confirm what the perceived rate of effort tells me. And thus it also gives me confidence to continue doing what I have done so far: If it feels too hard, back down.
I’ll start keeping my lactate readings, together with notes on heart rate, perceived level of effort and some other parameters in a spreadsheet.
Here’s the HR plot of the session:
