From Mike Young’s splits on elitetrack, this is the time to the END of peak speed (i.e., until you start slowing down):
Ben 60m (0.83)
Carl: 60m (0.83)
Tim 60m (0.83)
Mo 70m (0.83)
Asafa 80m (0.84)
Usain 80m (0.82)
You can see the advantage of different techniques. Asafa and Usain got their advantage over Ben and Mo late in the race. It’s when you end peak speed that really matters, and this is what drive phase methods are really about.
