Interview with Jenny Hartley

In this episode of The Focused Mind Podcast, Stu Holliday is joined by ultra-runner and doctor Dr Jenny Hartley, fresh from her victory at the legendary Summer Spine Race and a career that also includes multiple Invictus Games gold medals. Together, they explore the psychology behind thriving in some of the world's toughest endurance events. Jenny shares the mental strategies that have shaped her journey—from a 20-year military career to becoming one of Britain's leading ultra-runners—and how she developed the confidence to continually step outside her comfort zone and pursue new challenges. The conversation covers: How she prepared mentally to win the Summer Spine Race. Managing her inner critic using the Chimp Model (and why she calls her chimp "Stan"). Coping with extreme endurance pain and fatigue. Maintaining focus, motivation and optimism during races lasting more than 100 hours. How psychological skills influence not only her running, but also her work as a doctor and everyday life. Jenny also discusses her experience using The Psychology of Running, explains why cold-water swimming has become such a powerful mental training tool, and shares how she helps both athletes and patients overcome fear, embrace discomfort, and build lasting resilience. Whether you're an endurance athlete, healthcare professional, or simply interested in the psychology of high performance, this episode is packed with practical insights into developing a stronger, more resilient mindset. We hope you enjoy the conversation!
