In this episode of the Run the Riot Podcast, we discuss the concept of the 'pain cave' in ultra running, inspired by a conversation with Philip Klinkner. We emphasize the importance of mental preparation and creating a supportive environment before facing challenging races. We share insights on how to mentally prepare for tough moments, using mantras, motivational quotes, and past successes to build resilience. We encourage listeners to prepare their 'pain cave' in advance, highlighting the significance of mental training alongside physical training.
