FAT VIKING is a WINTER ULTRA ENDURANCE event under somewhat more « controlled » circumstances than the Iditarod Trail Invitational. The race course runs on snowmobile tracks, dogsledding trails, snowcovered roads and cross country skiing trails around Geilo/ Skurdalen/ Dagali. Checkpoints are inside a heated building where basic food (oatmeal) is offered along with the opportunity to rest. Several « bail out options » along the route are available in case of emergency/ abandoning the race.
