The UK’s favourite fitness coach is back with series three of his podcast. This summer, Joe is speaking to inspirational friends and some of his favourite people to ask them what they do to keep themselves feeling mentally and physically strong.

In the final episode of the series Joe speaks to someone who, one afternoon, inspired Joe to leave his house and run a marathon across London, eventually coming home after dark. It's the author of Born to Run and former war correspondent, Christopher McDougall.

Chris’ story begins with a persistent foot injury, which meant he was told by doctors he would never run again. Then Chris came across an extraordinary group of people in Mexico – the world's greatest distance runners, who run into the old age without rest or injury. He tells Joe about learning to run with the Tarahumara Indians – and what made the tribe such incredible athletes. Chris took on the challenge of joining them on a 50-mile race through the canyons.

Joe and Chris discuss how to get into running as a beginner, tips for perfecting your form, why you should find your tribe and how to keep the play and fun alive.

This is sunshine in a podcast. Joe Wicks is here for you, and he won’t stop until you’re fit and happy.
