Competitors need to be in peak physical condition to take on this gruelling challenge. The 160km (99.5 miles) Classic Arctic Circle Race ski route goes through beautiful arctic landscapes, 65km (40 miles) north of the polar circle. There is also the ACR 100, a shorter race of 100km (62 miles) covering similar terrain. The main race itself takes only three days, with the rest of the time given over to vital preparation, a Greenlandic church service (it is a Greenlandic tradition to start major events with one), and a gala party.
