The boys are back for another week, and this time we are joined by Leigh Wallis.

A motorcross champion in his teens, followed by a long hiatus from competitive sports until he discovered running and inevitable, triathlon!

After completing Ironman Wales a few times, and understanding the physical demands, Leigh was struggling to find his mental breaking point. And then, the 444 Challenge was born.

4 Iron distance triathlons, in 4 days across 4 countries. That might just do it.
