400stud – by what to train inline with the 400, I didn't mean "200 speed" I mean pure max velocity, like in flying sprints. My thinking being along the same lines as rice773, that a speed reserve factor would be very nice.
a whole year on 200m, overall doesn't sound like a terrible idea. kind of like a short to long plan done over a couple years. I think it would be good because it would allow one to reach a new top speed, and raise the ceiling for the future. But one would need a big gain if they focused a whole year on the 200.
what about something more conservative like focusing on the 200 specific components through preseason, a big chunk of winter and not introduce 400 specific endurance stuff until late?
