What is The Norseman triathlon?
More than 6,000 people from 96 countries applied for one of the 250 slots in this year’s race and they will begin their jaunt around the Norwegian countryside with a dive into one of Norway’s most picturesque fjords.
Starting from the loading bay of a car ferry, the competitors will swim through the fjord to the local town of Eidfjord, and the first transition. Then it is on to the bike, where they will tackle a challenging course through the mountains before the run up to Gaustatoppen, which sits at 1,880m above sea level.
The race record for the full distance is 9:52:10 by Lars Christian Vold (Norway), set in 2017 for the men and 11:16:10 by Mette Pettersen Moe (Norway) in 2018 for women. The majority of the competitors come from the home country, with a handful travelling internationally to tackle the near mythical race.
However, Jon Sæverås Breivold set a time of 9:09:57 in 2023, albeit with a shortened run (32.5km) due to thunderstorms. That same day Sebastian Kienle recorded a time of 9:34:16. Colledge also set a time of 10:10:16 in the women’s race.
For the few who make it through the race to the summit at Gaustatoppen, a black finisher’s T-shirt awaits them, the only recognition for taking on and conquering one of the hardest endurance races in the world.
