Known as the Iron Cowboy, James is an endurance athlete who has breaking records for years. In 2012, he completed 30 Ironman triathlons (2.4 mile swim, 112 mile bike, 26.2 mile run) in one year. No one had ever done anything close to this. In 2017, he did the unimaginable, completing 50 Ironman triathlons in 50 consecutive days in 50 different states, all while raising money to reduce childhood obesity. It was an amazing physical feat, an astounding logistics challenge and fair bit of chaos, all at the same time. You can watch the trailer here for the critically acclaimed Amazon Prime documentary; Iron Cowboy | The Story of the 50.50.50. But that wasn’t enough. In 2021, he pushed further, a lot further, beyond what doctors and physiologists thought was humanly possible, and completed the CONQUER 100…100 Ironman distance triathlons in 100 consecutive days, this time raising money to combat sex trafficking. That’s 140.6 miles per day, every day, for 14 straight weeks, for a total of 14,060 miles!
