Having gone through USATF Level 1, the biggest talk amongst us in the crowd was talking about program design. When asked, the presenters said “that is what networking with other people is for.” Essentially the blind leading the blind.
By far the most common question on this forum is program design. I think a “problem solving” for program design would be interesting. In SPP, Charlie briefly mentioned reaching goals etc, but never dug into specifics on fixing it at that point. So essentially, those who are students of sprints and study many coaches, are left to find common themes among these coaches and try to figure out how to organize them into a training plan for the athlete(s) we have (as coaches).
