.75 of 1/4 - That's about how long it took me before I was breathing sooooo hard I had to quit the race. I lost to PT1 in a quarter mile sprint today, in 90 degree temps. I stayed about one yard behind him (you know drafting), planning to pour it on in the end. Just about the time when I should have "poured" it on is about when I went from "running" (if you can call it that) too slower than a crawl as I watched PT 1 pull ahead to the finish line. New goal be able to beat PT 1 in a quarter mile by end of summer!
