Endurance Training Cycle Phase 1 – Microcycle 2 – Friday
11 mile run at 80% max HR w/1-minute plank every mile.
This run should be just past the point of being uncomfortable and the planks will suck. The planks don’t have to be exactly on the mile, just make sure you have 11 total minutes by the end.
You might ask what the planks have to do with improving your run…
It’s just to save time.
