The Inferno Triathlon with its 5500 metres of ascent is one of the toughest in the world.
This incomparable encounter with nature on the route from Thun up to the top of the Schilthorn via Interlaken and Grindelwald makes it one of the most impressive sporting challenges ever.

The Inferno Triathlon is a triathlon that has been held in August in the Bernese Oberland since 1998. Compared to many other triathlon events, the necessary infrastructure is not provided at a central point, but the start, transition area and finish are located at different places. With 5500 metres of ascent over a distance of 155 km, it is very challenging.
