Set in the untamed wilderness of Denmark’s northwest coast, the Cold Hawaii Ultra 2025 takes place on September 20 and offers five distances: 12 km, 24 km, 50 km, 50 miles, and 100 km. Runners traverse a dramatic mix of dunes, heath, forest trails, and shoreline as they follow parts of the historic Redningsvejen, a lifeboat trail. The 100 km route begins in Bulbjerg, with the first 20 km requiring GPS navigation before joining the main marked path toward Agger. All races culminate at Vesterhavshytten by the North Sea, with shuttle transport provided to the start lines. This event is as much about endurance as it is about immersion in Denmark’s coastal landscape.
