I skipped my 30 minute recovery session last night because a meeting went late.  This morning, my legs still felt heavy and my arms were sore, I guess from working at higher rates.

Anyway, the plan was for a 4 x 20′ at 190W (on slides), but I had a suspicion from the start that it was not going to be smooth sailing.  I was right.  My HR climbed fast, and it felt like really hard work.  My HR drift was 5% from 40′ to 60′.

When I finished 60 minutes, I did a lactate test and scored a 2.8mmol/l.  Compare that to 1.7 for the same training power on Wednesday.  I even did the test again to confirm the reading and the second test was 2.4mmol/l.

With that, I decided that another 20 minutes would do more harm than good and called it a day.

Tomorrow:  HM at Threshold
