Rosie Maclennan is the only person to have won back to back Olympic gold medals in Trampoline. The way she sees it, that's history. You can't change history, can't take it away, no matter what you do in the future. So when it comes to Maclennan's approach to Tokyo 2020, call it a threepeat if you want, but that won't change her plan of attack: to be the best she has ever been on trampoline.

Which is not to say that Rosie makes light of her legacy. Maclennan is proud of the fact that a whole generation of young athletes joined the sport because of the example she set. She tells host Anastasia Bucsis about her work with Right to Play, The Gist, and other female sport initiatives. The involvement goes well beyond lending her name to good causes. Maclennan recently earned a masters degree, focusing on Athlete's rights and responsibilities, and she ploughs into the work with serious purpose.

Maclennan is also extremely persuasive on the matter of physical literacy in Canada's schools. She's at the peak of her game, in every sense… The concussion-like injury of several years ago is no longer a problem and a recent foot fracture is healing nicely.

Rosie has written about her recovery from injury for CBC Sports' Player's Own Voice essay series.
