Usain Bolt and Michelle Bolt

"If you're living in a 100-meter, 200-meter athlete, and Usain Bolt is there, you have no chance," he says. "We need to just make sure that we're going to have categories to make sure that everyone sort of starts with this at the same level or with the same ending cap" He adds: "I don't think this is ever going to happen but if you're just playing hypotheticals, that's where people say, well, that's not fair"
