It depends on where the athlete is in the mesocycle but for a strength-endurance phase it’s usually less than 180-240 yds (they have to be able to produce speed and power during their lifting session after all). On page 39 of Mr. Francis’ Key Concepts book he has a sample program that looks like this (I omitted the sample med.ball throws and weights as they aren’t relevant):
Monday:
Speed: 2x3x20-30m accelerations (at least 4 min rest between reps).
Obviously we’re not training 100m sprinters so the distances have been adjusted to reflect the 40m acceleration distance for bobsledders where the initial impulse is the most important part of the race. However, the volume is fairly close.
