ENDURE THE EXTREME | Asi Ultra Marathon 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! 

At some point, it stops being about the distance.

The body keeps moving, but the mind goes somewhere else into the silence, into the landscape, into something deeper.

Across 100 miles of Arctic wilderness, the runners of the Asi Ultra Marathon experienced more than a race.

They experienced something that stays with them long after the finish line. 🌌
