Act like a champion, talk like a champion, run like a champion. Wired like a prizefighter, Donovan Bailey became the fastest man on earth in the 1990s.   He did it for himself while raising Canada's standing in international sport. In his memoir, the 100-metre and Olympic and world gold medalist tells his life story with intent.

Rooted in Jamaica and then Oakville, Ont., Bailey rocketed around the world after a belated entry into athletics. Following his triumphs on the track, his career was derailed by injuries. Decades after retirement, he makes it clear where he stands in the pantheon of Canadian sport. All you need to do is read the title — Undisputed: A Champion’s Life.
