    We know there's no 'kick' in a 100. There's the ability to hold speed. That is a form of endurance. That kind of endurance is mostly genetic (Herb Washington and Houston McTear did not have it naturally), but there is a training component also. It's trained in 150m repeats. As we often hear, there are phases in the 100: block clearance (0-10m, Gatlin's toe-drag is one technique), drive (acceleration from 10-60, a forward lean with the knees rising higher), top-speed maintenance (60-90, requires relaxation), deceleration management (90-100, where many races are lost because proper form is not maintained).

    There's lots of terms for what is happening, but I would consider 'speed-endurance' a factor, even in the 100. In the 60? No. The only kick that exists in track is when someone running at an aerobic level, accelerates to an anaerobic level. Even David Wottle in his famous 800 'kick', was not kicking, everyone else was slowing down and he was 'maintaining'. Some people actually do speed up at the end of a sprint race (100/200/400). All that means is that they were running sub-optimally before then.
    The entire premise of speed reserve is to have a max v so high you can skim under the ceiling and maintain higher speed for a longer time. 150m repeats aren't going to turn 0.85/0.86 into 0.83/0.84. Fly runs and EFE or FEF are the best for this.

    Carl hit 1.70 80-100m in Stuttgart 1993 (10.02) as his best 20m section. Was he running sub-optimally before that point? I certainly wouldn't say so.
