World’s Toughest Mudder

 24 HOURS.

World’s Toughest Mudder is the most extreme, insane, imposing, pulse-pounding, heart-stopping 24-hour obstacle course challenge on the planet. The man, woman and/or team (2+ participants) that completes the most 5-mile course laps at this outsized event in a 24 hour period will be crowned champion. Individuals and teams who complete 25, 50, 75, or 100 miles will be honored for their efforts. World’s Toughest Mudder is open to athletes of all levels. However, to be a contender for prize money competitors must be a top finisher at a 2017 Toughest Mudder event.

Race Format

World’s Toughest Mudder 2017 is a 5-mile circuit race peppered with 20-25 of Tough Mudder’s biggest, baddest, most insane obstacles, including never-before-seen 2018 obstacles and a handful of World’s Toughest-only obstacles, at a rate of 4 tougher-than-you-ever-thought-possible obstacles per mile. “The Pit” is where competitors set up camp in order to rest, recharge, and refuel during the event, aided by up to 4 “Pit Crew” members per participant. Event winners will be the man, woman, and/or team that complete the most laps in a 24-hour period.


The course is designed by the same mad (sadistic is a little strong, but it’s close) minds that deliver Tough Mudder’s world-class obstacles and events every season. However, whether you’ve completed one Mudder or 200, you’ve never encountered obstacles like the ones you’ll find at World’s. In addition to debuting out of this world (see what we did there?) obstacles that’ll be found on course at 2018 Tough Mudder events, this insane course features exclusive obstacles tailored to the harsh landscape and 5 unique miles of World’s Toughest Mudder.


While this event, unlike a regular Tough Mudder event, has winners, it does not have losers. World’s Toughest Mudder is a challenge that brings together and celebrates the worldwide obstacle course community, as well as Mudder Nation. Laps may be tracked, but the same core Tough Mudder values – teamwork, camaraderie, and leaving no Mudder behind – ring truer than ever on this course. Adding to the camaraderie, the course features “The Pit” – an area where all participants and “Pit Crew” camp, sleep, recover, and refuel.


Located 35 minutes from the Las Vegas Strip (the event’s first major obstacle is leaving the partying until afterwards), and just 30 minutes from Las Vegas’ McCarran International Airport (LAS), Lake Las Vegas is an ideal venue for the 2017 World’s Toughest Mudder. The site contains several hundred acres of rolling desert landscape, which runs alongside a massive freshwater lake. Natural terrain features including the lake itself will be incorporated into the course design, with temperatures assured to fluctuate significantly between day and night.
