Yeah, just run out of power, at the end of a ramp test I just can’t turn the pedals anymore but no burning sensation. My lungs are going mad like the end of a well paced HC, huge gasps of air, but no burn. Maybe I’m limited by CV system rather than lactate.

How do your legs feel at the end of say, a 1-1.5 minute 200% FTP effort (maybe 550-600w)?
In my case, my lungs are on fire, my legs feel like they are wooden logs that are on fire, and further pedalling feels like I am trying to pedal through leg cramps.
If I get off the bike, I have to hobble around, until the aching dies down.
Perhaps I am CV system limited for example I know that at the moment, my leg endurance/repeatability/HR recovery is rubbish, though I can put out ok power at anaerobic and vo2.

Yes, similar feeling to how your abs might feel doing 10 more sit-ups than your previous max.
How do your legs feel just before they stop working? Just tired?
