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

The ESN Hybrid Games - R.I.S.E. was a hybrid fitness race presented by ESN (Elite Sports Nutrition) at Forders Gym near Birmingham, UK, on 29 March 2025. The organisers billed it as ESN's first fitness race in the UK. R.I.S.E. stands for Resilience, Intensity, Strength and Endurance.

The race featured seven stations, including running, rowing and farmers carries. It offered several divisions: a Pro Athlete division with heavier weights for experienced fitness racers, and an Athlete division with lighter weights for those newer to the sport. Participants raced alongside a group of invited elite hybrid athletes, with cash prizes from a stated £10,000 prize pool across divisions. No later editions or official website for the event could be found, so race.fitness lists it as a single past event rather than a running series.

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.
