Description

What on earth does it take to complete 100 Ironmans in 100 days? James Lawrence – aka the Iron Cowboy – joins the podcast to share the physical, mental and nutritional toll of his epic Conquer 100 challenge. Spoiler: it involved over 12,000 calories a day, a few Costco muffins, and being fed through a massage table hole.

Whether you're a beginner or a seasoned triathlete, James drops some absolute gold on building resilience, fuelling with real food and why consistency beats perfection every time.

We talk about;

  • Meet James “Iron Cowboy” Lawrence

  • Why 100 Ironmans? (and how it started with a 4-mile fun run)

  • The perfect Ironman day and the role of nutrition

  • Real food fuelling: burritos, pizza, steak on the run

  • Caloric needs, gut training and sugar overload

  • What went wrong when fuelling slipped

  • Mindset, purpose and managing pain through adversity

  • Blue collar habits, unsexy consistency and building a strong foundation

  • James’s current nutrition approach and fuelling tips

  • Meet the support team and key recovery strategies

  • Advice for age groupers struggling with motivation or consistency

  • What’s next for James (hint: it’s not 200 Ironmans)
