My limiting factor in this crit right now, physically, appears to be my HR and lungs. My legs never gave out, but my HR was through the roof, I was gasping for breath, and my mouth had dried up so much I couldn't swallow without taking a sip. And sips were tough to grab going flat out in the drops for so long. The course has a rise leading to turn 1, then it drops down into turn two, with a long flat section to turn 3. When things are calm, people ease up a little going up to preserve strength, accelerate going down, and maintain that on the flat. When it heats up, they are flying up the incline, powering hard back down, and attacking leading up to turn 3. The last couple of times doing this course, my legs would give out when we were pushing it hard on the rise. I couldn't match the pace. I did much better on that this week. I had the legs and pace; I just couldn't breathe after a few laps of that!
