Yo.
I was wondering if anybody could tell me where I can find estimates of how fast a runner must be for his/her running speed not to be limiting at different distances.
For instance, if I wanna run 800m, how fast must I be running 60m, 100m and 200m. If I wanna run 3000, how fast must I be able to run a 200m to stand a chance. (I am only talking about speed here, not getting into other parameters like endurance.)
