Speed endurance the key to *all* 11/12second sprinters?

Hmm… the best improvement Bolt got over this past season was in his first 30m (intraseason, not overall)… so is he really doing S-L? Race after race after race he had bad starts and was in line with far lesser athletes to 20-30m and then he moved to the front of the pack when WCs came along…

Martn, nowhere in any of the products Charlie sells does he show a triple periodized schedule. The schedules he does have of triple periodization don’t look a thing like what Bolt is doing. Most of these guys don’t have any serious competitions until at least May and aren’t doing much tapering at all. Except for Gay in '07/'08, they don’t even have to run their nationals hard.
