This is not a city run.
The Asi Ultra is a 3-day, 100-mile journey across an ancient Greenlandic snowsled path from Kangerlussuaq to Sisimiut.

This ruthless route takes you across raw Arctic tundra and frozen sea ice, in the challenging polar conditions of -20°C. No crowds. No shortcuts. Just you and the Greenlandic wilderness.

It's an extreme endurance run, that will leave you with memories to last a lifetime - moments only a handful of people get to experience.

The run is part of an all-inclusive 7-day package, providing accommodation in Greenland, inland transfer, international flights (to/fr Copenhagen), safety training, gear transport and officials on route.
