Durability in Endurance Sports

The very best cyclists have unbelievably good durability. They drop off very little, no matter how much fatigue they accumulate. It's because they've got fast-twitch muscle fibers and biochemistry and neurological systems that allow them to just generate more power over 30 seconds than he ever can. So why is fun a pull and fun art the sprinter guys at the end of a cobbled classic? And Pragacha knows he can't bring them to the finish.
