Trail 45 Km

WELCOME TO ECOTRAIL STOCKHOLM 45 KM!

Challenge yourself in one of our two ultra distance races race where you run on beautiful trails through nature reserves, along beaches and past castles before finishing in beautiful surroundings on Norra Djurgården. The experienced ultra runner will be challenged by fast international and local runners, but for most of the participants it's more about finishing, regardless of time. Our 80 and 45 km races are semi self supported and most runners will bring a backpack containing extra food, water and other equipment they might need throughout the day.

Our cut off times are very generous and you have 10.5 hours to reach the finish line, so challenge yourself in a full-day adventure in running shoes, be inspired and up-lifted by fellow runners and our cheering volunteers and run further than you've ever done before. The number of slots in the race is limited to 400, so secure your spot in the race today!

THE COURSE

Our 45 km course gives you all the best of what Stockholm's got to offer when it comes to great trail running - archipelago, technical single track trails, country side, city, sights and several view points.

For the 2022 race we updated the course and the new course offers even more beautiful nature and single track trails compared to the course for the previous editions.
