3. Tough Mudder Infinity
Best for: Endurance Athletes and Those Looking for a New Challenge
Tough Mudder Infinity is a revolutionary event that pushes athletes to their physical limits. Unlike traditional Tough Mudder races, which focus on completing a set course once, Infinity is an endurance challenge where participants complete laps on a specially designed course within a fixed amount of time.
What to Expect:
Format: Participants race on a 3 to 5-mile lap that incorporates a variety of obstacles. The goal is to complete as many laps as possible within a set time frame (8 hours).
Obstacles: Expect to encounter a mix of traditional Tough Mudder obstacles like "The Block Ness Monster," "Kong Infinity," and "Arctic Enema." The obstacles are designed to challenge both endurance and skill, with different ones being repeated across laps.
Strategy: Since it’s about completing as many laps as possible, pacing becomes a key factor. You’ll need to balance speed with recovery to maximize your performance while preventing burnout.
Training Tips:
- Endurance is key. Focus on building your stamina through long, steady-state runs, as well as endurance-based strength training.
- Simulate the event by doing time-based training where you work through obstacle circuits with minimal rest.
- Practice mental toughness — this event can be a grind, so staying focused on completing one lap at a time will be vital.

4. Toughest Mudder
Best for: Hardcore Athletes and Endurance Enthusiasts
Toughest Mudder is one of the most demanding OCR events in the world. It’s a timed, overnight challenge that tests your limits with continuous laps over a 12-hour period. The event is a true endurance race, combining running with tough obstacles that demand strength, speed, and mental grit.
What to Expect:
Format: Participants have 12 hours to complete as many laps of a 5 mile course as they can. The course is designed to challenge you both physically and mentally, with signature obstacles like "The Everest," "Electroshock Therapy," and "Funky Monkey."
Obstacles: Expect a full mix of Tough Mudder’s most iconic obstacles. With each lap, you’ll face the same obstacles, but the fatigue and night-time conditions will make each one feel increasingly harder.
Night Racing: Some Toughest Mudder events are held overnight, adding an element of fatigue and mental strain as participants race in the dark.
Training Tips:
- Train for long endurance events by running long distances while incorporating hill sprints, strength training, and obstacle-specific drills.
- Practice running at night or in low-light conditions to simulate the experience.
- Train your mind to push through extreme fatigue — mental toughness is just as important as physical endurance in this race.
