Oslo Trail Challenge

About this event

The Oslo Trail Challenge takes runners deep into the Norwegian wilderness surrounding the capital, with three demanding distances that test endurance across rugged Scandinavian terrain. The 55km route brings 2000 metres of climbing, while the 100km and 200km options double and quadruple the challenge, with the longest topping out at 8000 metres of ascent. Set in late September when autumn colours paint the Norwegian forests, runners navigate technical trails through dense woodlands, rocky ridges, and remote valleys. This is an event for experienced ultra runners seeking a serious test in Nordic conditions, where weather can shift quickly and self-sufficiency is essential.
