Our 400mtr rep session was slightly different tonight... 12 reps, split into 4 sets of 3 reps, each set getting approx 5 seconds quicker.... only 20 seconds rest after, rep 1, 40secs after rep 2, and 60secs after rep 3....
The aim being that by the 4th and final set of reps you are up to your “normal” rep pace... therefore the first three reps should be approx 15secs slower than your usual pace....
My target was 95secs for the first set, then 88, then 83, then 78....
My times were. 95, 95, 88(!?), 86, 86, 86, 84, 83, 83, 80, 83, 82....
The 20 second rest periods were over in a blink, barely enough time to wipe the sweat out my eyes and check the watch.... the 40 secs rests were little better, the 60secs rests were nice but then having to speed up, and straight back down to 20secs rest again, made it one of the toughest sessions I’ve ever done.... by the final three I just couldn’t get down to usual pace....
In short, 400mtr rep sessions are tough enough, keep them simple unless you really know what you’re doing... I am wrecked tonight!
