Clyde Hart is known for his quarter miles athletes from Micheal Johnson and Jeremy Warriner. He believes that Jamaican sprint sensation Usain Bolt has the ability to run below 43 seconds for the 400m event

The Baylor University coach said that running a world record 42 seconds for Bolt is plausible with the right training and conditioning

Coach Hart, “Yes, I think certainly if he (Bolt) had the right programme, with his speed, he could run under 43 seconds, but whether he would ever do that is a whole different ball game. When we talk about potential, I always use a formula. You double a person’s best 200m and add 3.5 to it and that should give you what you are able to run the 400 metres”

He added, “If they have the work ethic, motivation and all the condition to go with it you could see that Bolt would be running in the 42s. You need to recognise there is more to running the 400m than physical ability because in the past there have been some very fast people who have tried the 400m and didn’t run very spectacular times”

Commenting on MJ, “The same thing was true with Michael, although he had (a 400m best of) 43.18. I still think his potential was down in the 42s. He would probably have done this had he ran the pace he was running (in the 1999 World Championship 400m semi-finals) but he didn’t attempt to go for the world record until he was well on into his career”

The current world record is 43.18 seconds by Johnson and Usain Bolt has a personal best of 45.28 seconds in the 400m and Bolt’s last 400m race this year he made it look easy and ‘jogged’ to a 46.94 seconds timing
