I am training for a 60M sprint in Dec. Currently, my coach is advocating conditioning: we work out for over two hours; perform lots of sprint intervals, drills, technique, and then finish with more intervals. I am new to track, so keeping up with guys who competed their whole life is challenging. I seem to pushing my aerobic capacity more so than my anaerobic. My question is this: Does it make sense to keep sprinting if your times are slowing down during the course of practice? It seems to me that over training may occur if I am getting slower by the end of practice. I don't have the endurance to keep up with these guys, but if I come in fresh, with my explosive start, I can overpower them to the finish. Oh, I am a natural athlete, early 20's, with an intense weight training background -any advice or routines would be appreciated.
