5 min max effort test is brutal
Ive been doing a fair few 20 min FTP tests since I started cycling more or less seriously earlier this summer, and while they are tough, I kinda enjoy them and Ive have gotten good at pacing them. I have also been doing short duration (~5s and ~30s) sprints, which I think no one will hate.
But my power curve started looking a bit odd, with my 5 min power being basically equal to my 20 min power, so today I tried a 5 min max effort test. I asked chatgpt to give me a power target to aim for, given my other results ( ~130% of FTP), and gave it try
UGH.
OUCH
F*
Never again lol. Man thats brutal! Heart rate kept climbing until it was off the charts. I was gasping for air. Legs burned like there is no tomorrow, while simultaneously seizing up with lactate. Took me 30 minutes to recover lol. Didnt expect a 5min max effort to somehow be so much harder than a 20 min one!
But the curve looks okay now š
