Well, although my title was 2 x 200m sets, I am sure I now remember it as John stated ie. 200 + 200 with very short rest. I am however, thinking it was one of Charlies not KKs.
Either way, wouldn’t come home pace be too slow for the reps? This would make for an easyish 400m.
I am keen to find out what the actual session was since i remember doing it and the lactic biuld up in the hamstrings was greater than from any other session. That’s good isn’t it!
