Tough Mudder vs Toughest: distancia, estaciones, precio y dificultad comparados (2026-27)

Tough Mudder is an obstacle course event series founded in 2010 by Will Dean and Guy Livingstone, with its first event in Pennsylvania, USA. It has been owned by Spartan Race since 2020. Events are held mainly in the United States and Canada, with regional editions in the UK and other countries.

The main formats are Tough Mudder 5K, with 12 or more obstacles, and Tough Mudder 15K, with 20 or more obstacles over a 15 km course. Infinity events and the World's Toughest Mudder are 8, 12 and 24-hour endurance challenges. Signature obstacles include Arctic Enema, Mudderhorn and Electroshock Therapy. Tough Mudder is built around teamwork rather than finishing times, and most participants sign up as a team. The 5K suits newcomers and groups, while the 15K and endurance formats call for solid running fitness and upper-body strength.

Toughest is an obstacle course race series held in Sweden and Norway. The organisers report more than 220,000 runners since 2013, and the race has repeatedly been voted the best obstacle course race in Europe in runner polls.

Each event weekend offers several formats. The Main Race covers about 8 km with the full set of obstacles, and Double Distance is two laps of that course, about 16 km. Xplore is a 4 km version with the hardest obstacles removed and no timing, aimed at first-timers, and Toughest Family is a 2 km course for children and adults together. An Elite class runs the 8 km course for competitive athletes, with the Toughest Tour and OCR World Championship qualification. Courses mix grass, sand, gravel, mud and water, with signature obstacles such as the Ramp and the Holmenkollen. Current venues are Gothenburg, Malmö, Stockholm, Oslo and Sälen. Every finisher receives a medal.
