You mention 60m races being a good "check" for how the athlete has progressed through spp1 and for planning subsequent training/comps. My question is how you would do this for someone going L-S. Presumably the 60m result wouldn't be as good for someone doing L-S as it would be for those doing S-L so would you just race at 60m with "lower expectations"? Would you have them race at 200m? Something else entirely?
