For all that Alexi Pappas knew about her body in 2016 - enough to push it to setting records in the 10,000m event at the Olympics in Rio - she knew very little of her mind back then. What followed gave her a crash course in the critical role our brains play in any performance: suffering severe depression, she began to think of suicide, only saved by the intervention of her father. Now on the other side of her darkest days, she uses her filmmaking, writing and acting to show how mental health and wellbeing are inseparable from sustainable high performance, especially for those trying to climb their own Mt Olympus.
