A spectacular race in a magnificent mountain landscape

For the second time, an ultra race is being held at Tyin Filefjell! This race is for those who want to run truly long and steep!

Tyin Filefjell Ultra is a unique ultra-race. With the race date in early September, one can never quite know what the high mountains will bring in terms of weather and conditions. Conditions can be challenging, with rain, fog, and wind, but it can also be glorious autumn weather with clear sun and magnificent views towards Jotunheimen and Hurrungane's mighty peaks. Regardless of the weather and conditions, the course offers running over dramatic mountain ridges and through spectacular mountain landscapes.

Until New Year's, you can register at Early Runner prices, which give a 25% discount. Sign up now and join us to experience the ultimate race in raw nature and challenging conditions.
