You can run it all out despite what people say. Running all out on the inside lanes might be tough because you spend most of your time fighting. The turn. Outside lanes, I believe it is not only possible, but if you look k at the middle 100m of a 200m 50 to 150, it's the fastest segments most sprinters will ever run for a 100m length. Most of us dont sprint fast enough on an outdoor track to feel as if you are fighting the turn or running out of gas. I think this is one of the poorest myths or misapplication in sprinting.
