Every year, 300 of the world's wildest triathletes descend on the fjords of Norway to take part in the toughest race of their lives. The Norseman Xtreme Triathlon includes a 3.8km swim in icy waters, a 180km bike ride with 5000 metres of climbing, and finally a marathon up a mountain. We follow 3 competitors as they make their way through this epic challenge. Alan Hovda, a 3-time race winner who is chasing his 4th victory; GTN's own Mark Threlfall, an ex-professional who has always had his eyes on this event, but who has never before competed in an iron man distance event, and Ole Peder Moe who despite challenging family circumstances puts in the race of his life with some emotional consequences.
