S3E2 Greenland: Arctic Circle Race

Located above the Arctic Circle, this three-day cross-country ski competition is renowned for its extreme difficulty, largely due to the capricious weather. The grueling first day presents numerous challenges for the competitors, while a blinding white-out on the second day tests everyone's limits. As the final day approaches, a threatening storm disrupts the race, turning everything on its head.
