With no races around I find it quite motivating to do climbs of 20-40’ at a very hard pace, kind of QOM-chasing style.
My HR and breathing are naturally very high during these efforts. Actually I accumulate more time at >90% HRmax doing my favorite 32’ climb all-out than during my classical 4x8’ VO2max intervals.
Q: From a physiological point of view, can efforts like this (2x25’ FTP, 1x30-40’ all-out etc.) substitute standard VO2max sessions? (Obviously RPE is higher but motivation is higher too.)
[I’m very well-trained with several years of structured training; just to say that I’m not in the “whatever-you-do-will-make-you-faster” part of the population .]
