Toughest Stockholm 5 Jun 2027

Toughest Stockholm runs on 5 June 2027 in the Lida recreation area south of the city, a well-known outdoor spot whose varied terrain, the organisers say, meets every criterion for an excellent obstacle course race. The course sits within a nature reserve, so participants are asked to stay on the marked route and leave no trace.

Toughest is a Swedish obstacle course race series voted the best in Europe in several runner polls. The main race is about 8 km with the full set of obstacles, including technical Fast Lanes on selected obstacles for an extra challenge; selecting Double Distance at sign-up means two laps, roughly 16 km. Xplore is a 4 km, untimed course with the hardest obstacles removed for first-timers, and Toughest Family is a 2 km course where children and adults run together on obstacles adjusted for the youngest.

Registration fees rise through the registration period and entries close about a week before the event or when capacity is reached, so early booking saves money. Toughest suits everyone from first-time obstacle runners on Xplore to elite athletes chasing OCR World Championship qualification. Register on the official Toughest site.
