ASI Ultra Marathon
19 - 21 March 2026

ENDURE THE EXTREME

160 km | 3 days
Greenland
Ice

Experience unparalleled silence and total isolation, found only in the Greenlandic wilderness.

The Asi Ultra Marathon is a unique arctic stage race that leads you across frozen lakes, tundra, and sea ice in Greenland. No less than 160 kilometers over three days! 

The challenging trail is shaped by the paws of sled dogs in an ancient hunting ground that the Inuit have used for over 4,000 years. The race takes place in March, where temperatures normally range from freezing -5°C to -20°C. 

The sea ice is frozen solid, but the sun has begun to emerge after the long dark season, and at night, the Northern Lights dance in the sky above the campsites. 

This race is limited to 24 runners, will you be one of them?
