About the weekend
Trail running in beautiful Norwegian nature
Tromsø Mountain Challenge is a weekend of four cross-country races over three days in Tromsø. There are five races in total with two uphill races including a relay, an ultra race and two cross-country races. You can participate in a single race, or try your hand at the whole triple. The mountains of northern Norway offer great contrasts. Easy terrain and floating trails, steep slopes and rocky outcrops, marshy areas, green mountainsides and a beautiful view of the fjord.
