I spent 70 minutes on the indoor trainer, riding ultra-conservatively.
10 min w/u 88 RPM
10 min 66 RPM
10 min of 2 min 88 RPM, 2 min 66 RPM
1 min Stand @ 60 RPM
12 mins of 4 min 66 RPM,4 min 88 RPM
1 min Stand
3 min 88 RPM
4 min 66 RPM
8 mins of 2 min 66 RPM, 2 min 88 RPM
… or to put it simpler: I varied the cadence between 66 and 88 RPM a lot!
I feel in no way tired now; I might attempt a short easy run tonight.
