Hi Chris, I think that 2 week rotation should help, I still think that the speed volume in the GPP and SPP S-L is too much for 10.5 + athletes. I cut down the volume 2 winters back and it still wasn’t enough, my guys were trashed by mid december and raced badly in January. It was a bad experience so switched to L-S last winter but have set up the S-L with further reduced volume on both the hills and track work. I reckon it will work.
SPP1 Looks like this
Sunday Plio (vertical) + Weights
Monday Rest
Tues Speed + Weights
Wed Tempo 1500m
Thu Speed Endurance e.g. 2x4x60m + Weights
Friday Tempo 1800m
Sat Rest
Good luck with it all, keep us informed.
