… It is rare for an elite athlete running full out to maintain Vmax for more than 10 meters…
not to play on words, but when looking at data I consider that 10m split times maintained within 1 or 2 1/100s range to be (about) the same, so IMO elite athletes run at MaxV for more than 10 meters only…but rather anywhere from 20-40 meters usually.
here’s one quick example I Googled:
but I’ve seen plenty more of similar numbers over the years that support this at the elite level.
