He maxed them out, refusing to shift into the next gear until his RPM was just right. That allowed him to relax as he surged to the finish. He won because he stayed fast. But if you hit it too soon, you'll run out of gas. You've got to give your body enough time to unfold, so that you'll be in the best position to apply great force.
People think that all a sprinter needs to do is to run all out, but that's so Hollywood.
I want my sprinters to do just the opposite. I want them to show how easy it is to run fast. Haste doesn't win races. Taking your time just might. But sprinters are stripped of any such distraction.
