I did a Zwift race tonight, a local crit that has taken their events virtual during the COVID-19 lockdown. I averaged 98% of threshold for ~36m but my HR was ~196avg, 208 peak (final sprint). I’m 27 and this seems pretty high. Should I back down in the future? Is it dangerous to hold this kind of HR for that long? Anything I should do to recover from a particularly high HR effort like that?
My legs feel fine but I generally feel pretty smoked. A number of factors probably contributed to the higher than normal HR, but I’m thinking the main things were that I just got pretty hyped about the race start and then the 160%FTP blast for the first 40s or so followed by VO2max really peaked my HR and then I just couldn’t recover while riding between 95-110% for most of the race. Probably also could have warmed up better.
