Going back to the original thread. It does appear from the 400 s-to-l template that the components are pretty much in place for the athlete by the time the 12 weeks are up (and as was borne out by the 50.22 performance of the athlete). Where does the coach/athlete go from here in SPP2? Over and under distance work (e.g one session- 300’s another session- 500’s)? What about speed retention? The last 5 weeks saw the dropping of the 60’s and f-e-f runs. Does the athlete try to mix these in again even though the SE is intensifying further?
