DEKA vs Tough Mudder : distance, stations, prix et difficulté comparés (2026-27)

DEKA is a functional fitness race series run by Spartan Race and billed as the decathlon of hybrid fitness racing. Every DEKA event uses the same ten DEKA Zones. The time for each zone and the total time are recorded, so athletes can compare results with their own previous marks and with a global leaderboard.

The flagship DEKA FIT puts 500 m of running before each zone, for 5 km in total. DEKA MILE uses 160 m runs for one mile in total, and DEKA STRONG is the ten zones with no running. There are also DEKA Ultra (50 zones and 25 km of running) and DEKA ATLAS, a heavier ten-zone test with a 30-minute cap. Athletes who finish STRONG, MILE and FIT in one calendar year earn the DEKA Trifecta. Heats include Elite, Age Group, Teams and Ruck, so the series suits gym-goers as well as competitive athletes.

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.
