The Paris Olympics are less than a month away. The last games in Tokyo were one of the hottest on record, with more than a hundred athletes suffering heat-related illnesses. And France, the host of this year’s Olympics, is no stranger to heatwaves – the country has seen 23 since 2010.

So how are top athletes training their bodies to not only perform at their best in high temperatures, but also to protect their health? Presenter Qasa Alom heads inside a sweltering, state of the art heat chamber at Leeds Beckett University to find out how one of the fastest marathon runners in Britain, Phil Sesemann, is maximising his chances of success in his Olympic debut.

Other athletes are more used to these conditions. We join India’s top triathlete, Pragnya Mohan, for a training run and hear what it’s like to compete when the thermometer climbs above 45 degrees Celsius.

More and more athletes are adopting heat training strategies in a warming world - but do they affect men and women the same? Dr Jessica Mee, Research Fellow at the University of Worcester tells us about her pioneering research into the impacts of heat on women’s bodies.
