I'm wondering where peoples heart rates are for a sprint race in relation to your AT or max.
I read somewhere (that I can't find again) that the swim should be below AT if possible, bike 20bpm below and run 10bpm below. Is this for training or for an actual race?
I was not sure about spending time over my AT during the race, even though I know it's dooable as I sometimes run over AT at the gym for 5-10 mins of a run and regularly exceed it for short bursts mountainbiking.
my swim for sprint is z3 starting to touch z4, bike z4, run z4-z5.....i start the run running as fast as I can and just try to maintain pace. i never measured my HR but just go by perceived exertion....
i am always afraid to blow it up on the swim...since i am not the strongest in the water...yet
