Mind over matter, dig that.
I set a 20 min record during a FTP test back in May, if only by 4 watts, but still. I remember thinking that I was not going to think about how difficult or uncomfortable I felt, just that I was a machine and I was going to be operating at max output. At moments I was in some state of sadistic glee in the second half. As soon as I stopped pedaling, I puked a little bit on my bib shorts as my mind and body lurched from the effort. At 312 w and 150 lbs it was the fittest I've been since right after college, so for more than a few years.
Good times
Oh, and this was on Fiesta of course
