Talking with a couple friends and they mentioned that’s what they do. They race by “feel”. I never really thought of doing that. I think I’d over do it if I went by “feel” resulting in a shitty run.I race track, where you're not allowed to have a visible head unit (but you can put tape over it, or put it under your saddle to collect forensic data). So you have to get pretty good at measuring effort for pursuit or breakaway efforts.
My experience with running is that it's possible to get extremely accurate running by feel. And it's probably a useful skill at times. I remember way back in high school/collegiate track where the coach would prescribe a pace, say 12 400s at 72 seconds, and I could would cross the start-finish every time almost exactly at 72 seconds by feel.
