FATMAP difficulty grade
The Isklar Norseman Xtreme Triathlon is a 226 km swimming, biking, and running trail.
It takes you from Hardanger Fjord to Gaustatoppen in the breathtaking scenery.
But don't let this fool you: The trail is extremely challenging. The trail starts by jumping into the Hardanger Fjord for a 3,8 km swim in cold waters, followed by a 180 km bike ride over Hardangervidda National Park.
The final marathon run finishes with a brutal climb up to Gaustatoppen 1850 m above sea level. During the Isklar Norseman Xtreme Triathlon, nine out of ten participants make it to the finish.
But as the organization states clearly: It’s probably not for you.
