Inferno Triathlon

A tough race awaits Inferno Triathlon competitors, a race that has been held in the Bernese Oberland since 1998. Unlike other triathlon events, the necessary infrastructure is not provided at a central point, but the start, transition areas and finish are all in different locations. The triathlon starts in Thun, the transition areas are in Oberhofen, Grindelwald and Stechelberg, and the finish is on the Schilthorn. The half-marathon starts in Lauterbrunnen, and the athletes’ village is in Mürren, which is also the finish for the Team Trophy. Whether you take part in the triathlon yourself or cheer the athletes on from the side of the track, the Bernese Oberland’s impressive natural scenery will be your constant companion at this sporting event.

The triathlon begins with a 3.1 km swim in Lake Thun, followed by 97 km of road biking and 30 km on a mountain bike. It ends with a 25 km mountain run. With its 5,500-metre climb, the Inferno Triathlon is one of the world’s toughest triathlons. Alongside the actual triathlon, other less demanding disciplines are available. Competitors in the Inferno Team Trophy and Couple can take part in the triathlon in teams of two or four. The Inferno Half Marathon is a challenging 21 km mountain run up the Schilthorn. Beginners and less experienced athletes can also take part in the Mürren Fun Marathon.
