Ultra Obscura isn’t just about distance – it’s all about strategy. A course that will test your legs. A format that rewards much more than endurance. A race where planning and decision-making matter as much as strength. It’s pure trail running; nothing but trails, no asphalt, with a touch of the sinister.
Expect breathtaking views of the Sutton Mountains, technical and rugged trails that demand focus, and a unique format. Mental manipulation is present at every stage of the race. Emphasis will also be placed on sustainable trail running practices to preserve the cleanliness and beauty of Sutton’s magnificent trails. Only 200 spots are available. The race is organized by Sinister Sports and takes place at Mount Sutton.
