The course
We create a lap of 21,4 km on the frozen lake that you run once (21,4 km), or twice (42,8 km).
Frozen Lake Marathon is open to everyone. Every step is taken on pure ice in this beautiful event, which is limited to 500 participants. We guarantee the flattest elevation profile in the world and an experience you’ll never forget.
Tisleifjorden is located 819 meters above sea level in the Norwegian municipalities of Gol and Hemsedal in Buskerud and Nord-Aurdal municipality in Oppland.
For the most part, the ice on the lake is about 80 cm thick – with a carrying capacity up to 30 tons. A safe course is plotted by an assembled support team. The team monitors the course closely. The final course is laid out just days before the race starts.
Among other things, the lake is used for testing tires, emergency vehicles and drivers who want to test their skills in icy conditions. Now we let you take on the lake running!
