So this is in line with what I “feel” is the problem.
I feel my mind starts writing checks that my body cannot cash. I feel my legs are winding down, before I reach peak respiration/HR max.
Maybe it’s just will power? But as I’ve said, I can reach those states during other activities. And when I do VO2 intervals, I get nauseated and light headed, and generally feel real bad after doing them. So I hope I’m pushing hard enough.
So if I am not an adequately trained cyclist, what does this indicate I need to focus on?
