Am I in the majority where the hurdle to going harder is leg fatigue and generally not cardio fitness? Does this mean I need to do more leg strength off the bike?

I’m in the same place. I assumed that was true for everyone, but maybe I’m wrong. Some days Z2 just feels like Z4 in my legs and that’s when I know I need to rest. I also quit ramp tests because my legs can no longer turn, not because my heart explodes.

For what it’s worth, that’s my experience as well. It’s not the cardio that limits my vo2 or threshold; it’s that the legs can’t keep pushing. I’m doing some extra gym work increase leg strength this autumn in a hope to remedy this.

Great questions as there is too little info given. Add in recent training history (plan and workout types) and general discussion of fueling and recovery between workouts.

I have been in a similar situation with 2 minute v02 intervals. I can hit them well for about 4 reps then slowly fall apart. Poor sleep didn’t help a couple times and <90second efforts I can knock out repeatedly. Ill do a PL6.2- 1 minute interval workout and feel great, but 2 minute efforts at the s…

How fast do you spin? I have a friend who rides at 75 RPM, for him it’s all about legs. I ride at 95-100RPM, for me it’s cardio.

I took a poll on this a while back about why people stop the ramp test. Legs give out for the majority of people. [image] What is the reason you stop the ramp test? Training For me, it’s my heart can’t beat any faster - how about you? poll ————————————- Edit: added ques…

Disagree. Does anyone here in the middle of a training block come into workouts completely without leg fatigue?

You can surely be correct. I’ve got no idea about the science behind this. What I do have is the feeling that the legs can’t push the pedals, but the heart and breathing are “fine”, ie, not at max.
