EcoTrail Stockholm begins and ends at Stora Skuggans Amfiteater, with trail races taking place in Norra Djurgården and the greater Stockholm area on a June race day. The race distances range from children’s races of 700 m and 2 km up to 8 km, 16 km, 33 km, 45 km, and 80 km options, plus an 8 km Fun Run and a virtual version for those running their own route. Even the shorter adult races are mostly on natural ground, while the 80 km course features approximately 1,400 m of elevation gain and maintains about 90% of its route within natural surroundings.
The course combines technical forest paths with coastal sections, countryside, city outskirts, and Stockholm landmarks, catering to runners aiming for a fast time as well as those enjoying a long day on the trails. The organizer positions it as a race for all, and the variety of distances supports this: young children, casual runners, seasoned trail runners, and elite athletes can all participate. Participants receive a wooden medal, and the finish area offers food and a post-race gathering.
