This week Kenton welcomes Dr Sarah Ruggins back to the pod to unpick the details of her incredible bike ride from John O'Groats to Lands End and back again. Sarah blended her love of the discipline of unsupported ultra-endurance cycling with supported time-trialling to take on her most recent endurance challenge.

Sarah tells Kenton all about her approach to riding 2,700km at a speed most of us wouldn't be able to sustain for an hour, which resulted in her claiming the outright World Record for the route, completing it in 5 days, 11 hours, 14 minutes. She explains how her support team were integral to her success and how the riding was the easy bit - sleep deprivation and requirement for calories created far more of a challenge.

Sarah shares so many insights in this episode and we know you are going to love it!
