Mountain race for all levels

We are introducing an exciting new distance at the Mountain Festival: Børrenøse Skyrace – 7 km in spectacular high-mountain scenery. 

Børrenøse Skyrace is a mountain race for everyone, from experienced mountain runners to families and hikers who want an active Saturday trip together. Here you can take on the challenge at your own pace, whether you want to run for the best time, jog with a view, or simply walk the route as a nature experience in itself.

The 7 km long trail with 450 meters of elevation gain offers a true high mountain feeling, with the possibility of both rough weather with rain and wind, and sun and clear views towards Jotunheimen's majestic peaks. With its highest point at 1297 meters above sea level, you will experience both a sense of achievement and magical nature experiences, regardless of your pace.

Until the New Year, you can register at Early Runner prices, which give a 25% discount. Sign up now and secure your spot in this autumn's adventure!
