Trollveggen Triathlon is a mountain triathlon held in Åndalsnes, Møre og Romsdal. The race course incorporates the harbor, the Trollveggen wall, Isfjorden, and a steep ascent above the town. With a limited field of 200 participants, both transition areas are located in central Åndalsnes, allowing athletes to return to the same hub between the swim, bike, and run segments.
The swim takes place in the harbor basin, typically consisting of two 600-meter laps. Following the swim, competitors embark on a 53 km bike leg featuring approximately 600 meters of climbing.
