Arctic Circle Race in Sisimiut
A three-day, 160-kilometre cross-country ski race starting and finishing in Sisimiut, established in 1998 and run through mountainous Arctic backcountry in temperatures as low as minus 25 degrees Celsius, with more than 150 competitors camping overnight at a remote Base Camp between each of the three stages.
The Arctic Circle Race began in 1998, when a group of local visionaries in Sisimiut set out deliberately to create what they intended as the world's toughest cross-country skiing event, and the three-day race that resulted has kept that reputation ever since.
