no wayFrom an interview with Clyde Hart regarding the famous 200 workouts:
"Michael Johnson did eight in 28 in 2000 and he did the same in 1987. It is for training the body, it is not he couldn't go any faster. He could have been doing 5 in 25sec but where was he going to go? He would hit a wall. It is about the amount of work being done. You can use a whistle and a watch or a watch with a beeper.
"By mid-May it is 5 x 200m in 25sec for the top kids. If you have got five people per team you only get 1min 40sec rest rather than the 2min 20sec for the 35sec efforts. You have got to go faster with shorter rest. There are only a handful that can do five in 25sec. Michael got down to three in 23sec before Atlanta. He was taking 1min 30sec rest and did it from a dead start not a rolling start as a relay.
"Other kids have tried four in 24 and not managed it. It depends on how you time it. It should never be a race and never be a time trial. It is a progressive session.”
