From First 10K at 48 to Ironman: Jeff Weiss’ Endurance Journey

In this powerful and deeply relatable episode, Jeff Weiss shares how he went from starting his first 10K at age 48 to completing Ironmans, ultra marathons, and chasing the World Marathon Majors in his 60s. Along the way, he unpacks the mental battles behind endurance sport, the value of failure, and why chasing big goals reshapes how we see ourselves. From narrowly missing the cutoff at the legendary Comrades Marathon to discovering resilience through ice baths and yoga, Jeff makes a compelling case that racing isn’t just about fitness — it’s about identity, courage, and choosing a life without regret.
