A tribute to marathon runner Kelvin Kiptum and the science behind his record performances

A tribute to marathon runner Kelvin Kiptum and the science behind his record breaking performances.

A scientific tribute to to the successes and potential of Kelvin Kiptum, the best marathon runner to ever take to the roads. Marnie and the team take time to reflect on the tragic loss after Kelvin's death and looks at the science behind his record breaking performances. 

Why do East African long distance runners continue to dominate the world stage? Can one group of indigenous people in the state of Chihuahua in Mexico, really run 100km without getting tired? And what makes you fall off the back of a treadmill when you just can't keep going? Is the limiting factor in endurance sports found in the body or the mind? 

We also hear how one small insect is having a mighty impact on African ecosystems, and Marnie ponders the future of AI. What happens when we are no longer able to trust our eyes and ears in a world of deepfakes.

Presenter: Marnie Chesterton, with Philistian Mwatee and Tristan Ahtone
Producer: Harrison Lewis, with Dan Welsh, Tom Bonnett, Katie Tomsett and Jack Lee
