Tromsø Mountain Challenge, live.

Over the mountains and down Tromsdalen

Tromsø Mountain Challenge is a two day mountain running event in Tromsø, organised by the Midnight Sun Marathon foundation.

The 2027 edition is dated 21 August. The event is spread over two days and gathers the mountain races of the Midnight Sun Marathon organisation, with a finish in Tromsdalen on the mainland side of the city.

The La Sportiva Ultra is 50 km. It starts at Snarbyeidet, northeast of Tromsø, crosses mountains and open plateau and finishes at TUIL Arena after a descent through Tromsdalen. The organiser runs a bus from TUIL Arena to the start on Saturday morning. Participants must reach the Tromsdalselva checkpoint at 32 km within 5 and a half hours, and the total limit is 9 hours.

The La Sportiva HalvUltra is 25 km from TUIL Arena, with the same descent through Tromsdalen to the finish and a 6 hour limit. Dalheim Rundt is a shorter, more family friendly option, and there is a children's race as well.

The ultra and the HalvUltra are open to people aged 18 and over, while Dalheim Rundt has classes from 13 years. The organiser describes the mountains and plateaus as an experience in themselves for new participants and experienced runners alike, with demanding sections that test both strength and endurance.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and the official results come from Tromsø Mountain Challenge.
