Tough Mudder is an endurance event series in which participants attempt 10–12 mile-long (16–19 km) obstacle courses that test mental as well as physical strength. It was co-founded by Will Dean, a former British counter terrorism officer, and Guy Livingstone, a former corporate lawyer. The obstacles often play on common human fears, such as fire, water, electricity and heights. The main principle of the Tough Mudder revolves around teamwork. The Tough Mudder organization values camaraderie throughout the course, designing obstacles that encourage group participation. Participants must commit to helping others complete the course, putting teammates before themselves, and overcoming fears. An average 78% of entrants successfully complete the course.
The first Tough Mudder challenge was held in the United States in 2010. To date, more than 3 million people worldwide have participated in Tough Mudder events, Tough Mudder currently employs over 150 people worldwide.

Tough Mudder was co-founded in 2010 by Will Dean and Guy Livingstone, both British citizens living in New York. Dean had developed the idea for the company while studying at Harvard Business School, where the concept was a semifinalist in the school’s annual business plan competition. It has been noted that Will Dean took the idea from Billy Wilson and his Tough Guy races. Dean and Livingstone held the first Tough Mudder event on May 2, 2010 at Bear Creek Ski Resort near Allentown, PA. Promoted exclusively through Facebook advertising and word of mouth, the event drew more than 4,500 participants.
Two additional 2010 events were held in Northern California and New Jersey. The next year, 14 events were held throughout the United States. In 2012, 35 events were held in four countries. .
On May 2, 2013, Tough Mudder announced that it had reached one million total registrations since it started in 2010. The company had more than 700,000 participants in 2013, with events in the U.S., UK, Australia, Canada, and Germany. 2013 also saw the launch of Mudderella, a female-focused mud run founded by several Tough Mudder employees.
In April 2016, Tough Mudder announced a partnership with international sports management company IMG to bring its events to Asia and the Middle East, beginning with China and United Arab Emirates in 2016. Events in Japan, South Korea, and Singapore will follow in 2017. Tough Mudder also announced a partnership with media and technology investment firm Seroja Partners to host an event in Bali, Indonesia in October 2016.
On October 1, 2016 in Jimbaran Hijau, Bali Indonesia, Tough Mudder held its first event in Asia, drawing 1500 competitors from more than 37 countries including Jakarta, Singapore and Australia. On December 9–10, 2016, up to 5,000 participated in Tough Mudder’s first event in the Middle East that took place at the Hamdan Sports Complex. Tough Mudder CEO Will Dean revealed that the company will seek to launch a chain of fitness boutiques in the United States in 2017 to expand the brand beyond Obstacle Course Racing events.
In May, Tough Mudder did unveil its line of branded boutique fitness clubs, Tough Mudder Bootcamps, selling franchises. The Bootcamps will offer 45-minute HIIT classes that are designed to be done with a partner and center around four fitness pillars: strength, power, agility and endurance. 
In March 2017, Tough Mudder announced it was continuing its international expansion to New Zealand with Sports Media and Entertainment 360 (SME360) as the official licensee of Tough Mudder events in that country. The first event will held on November 4–5, 2017 at Hampton Downs Motorsport Park. Tough Mudder also expanded its 2016 partnership deal with IMG to include Australia for 2017 and 2018 seasons, adding to events already slated in China, Japan, South Korea, Singapore, and United Arab Emirates.
Will Dean was recognized in 2017 as one of the Sports’ “40 Under 40” by the industry’s leading publication, Sports Business Journal.
Dean has a book coming out in September 2017, entitled “It Takes A Tribe: Building The Tough Mudder Movement,” detailing his leadership of Tough Mudder, building the brand into a global company, the rise of the Tough Mudder “movement” and lessons he has learned.
Tough Mudder and Invictus Events and Entertainment announced in October 2017, that they entered into a new partnership to bring the Tough Mudder course and Tough Mudder Half course challenges to South Africa in 2018. This multi-year partnership marks the first time Tough Mudder has licensed its challenges in South Africa and on the African continent. 
The typical Tough Mudder course is 10–12 miles (16–19 km) long and features 20–25 obstacles. Terrain type varies from course to course; natural features of the land at each venue are incorporated into the course design. Past venues have included ranches, motocross tracks, and ski resorts.
The list of obstacles also varies from course to course, though there are several “signature” obstacles at almost every event, including:
- Arctic Enema – Participants plunge into a dumpster filled with ice water, dunk underneath a plank that crosses the dumpster, and pull themselves out on other side.
- Electroshock Therapy – Live wires hang over a field of mud which participants must traverse.
- Funky Monkey – A set of incline and decline monkey bars over a pit of cold water. The bars are slicked with a mixture of butter and mud.
- Everest – Participants run up a quarter pipe slicked with mud and grease.
Tough Mudder Half
At 5 miles long, Tough Mudder Half events are half the distance of a typical Tough Mudder challenge, with over a dozen obstacles. The courses feature signature Tough Mudder obstacles including Walk the Plank, Kiss of Mud, and Everest; however, they do not include any obstacles with fire, ice, or electric shocks.

World’s Toughest Mudder
World's Toughest Mudder is a 24-hour challenge. Unlike other Tough Mudder events, World's Toughest Mudder is a competition, with the top-ranking man, woman, and team receiving prize money.
The competition itself consists of a 5-mile (8.0 km) looped course, which participants continuously run through for 24 hours. The participant who completes the most laps is declared the winner. The winners receive the title of "World's Toughest Mudder" and a $10,000 prize for the winning solo male and female and a $12,000 prize for the winning team.
World's Toughest Mudder was first held in 2011 at Raceway Park in New Jersey. Junyong Pak claimed first place, and Juliana Sproles was the first female finisher. In 2012, Pak successfully defended his title. Amelia Boone was the first female finisher and the second finisher overall. The team competition was introduced in 2012; a team from Pennsylvania calling themselves “Nine Inch Males” took first place. There were over 1,200 competitors in 2012.
World's Toughest Mudder in 2014 was held at Lake Las Vegas in Nevada and was a 5-mile course with obstacles such as a 35-foot drop into a lake during the day and swimming 300 yards while keeping a torch lit at night. Top finishers in 2014 were Ryan Atkins (19 laps, 95 miles, male solo), Amelia Boone (15 laps, 75 miles, female solo), and Team Wolf Pack (15 laps, 75 miles, team). World's Toughest Mudder 2015 was again held at Lake Las Vegas, with the top finishers being Chad Trammell and Amelia Boone.
In 2016, about 1500 competitors from around the world converged on Lake Las Vegas for the third year in a row to compete in the World’s Toughest Mudder. New to the 6th annual running of the event was a $100K bonus prize for the first team to pass the 100-mile mark. Team GOAT Tough, consisting of Ryan Atkins and Jon Albon, took home the bonus prize and first-place finish by completing 105 miles (a record). In addition, all three men’s finalists surpassed the 100-mile mark (another event milestone) with first place going to Trevor Cichosz who also completed 105 miles. Stefanie Bishop, who signed up for the event at the last minute, took the Women’s lead early and never lost it, taking the Women’s crown by completing 85 miles.

Tough Mudder Bootcamp
In May 2017, Tough Mudder launched a studio fitness brand extension, Tough Mudder Bootcamp. The first two franchises, Las Vegas and Burlington, Massachusetts opened in April 2018. Franchises cost $50,000 with total startup cost ranging from $200K to $300K. Ten franchises have been sold and more than 65 have been reserved across the USA. The Bootcamps provide 45-minute HIIT classes for up to 24 participants each and are designed to be done with a partner and center around four fitness pillars: strength, power, agility and endurance. Classes are instructor-led with assistance from a proprietary technology platform that guides participants through each class station.
A person who successfully finishes a Tough Mudder event is deemed a “Legionnaire,” Tough Mudder collectively calls all its finishers the “Mudder Legion”. Each finisher receives a headband for completing a Tough Mudder. The headbands change color with the number of runs one has completed— orange for one, green for two, blue for three, yellow for four to six, pink for seven to nine black for 10 Tough Mudders or more. Tough Mudder created a handcrafted steel headband for the first legionnaire, Jim Campbell, who completed 100 Tough Mudders. 
In 2012, Tough Mudder founded an off-site “Obstacle Innovation Lab” in New Jersey, where the company designs and tests new obstacles.
In January 2015, Tough Mudder announced “Tough Mudder Redefined,” an initiative to revamp its courses by adding many new obstacles and updating the remaining ones. New obstacles for the year included:
- King of the Swingers – Participants use a pendulum to swing off a 12-foot platform and attempt to hit a bell before falling into a pit of water.
- Cry Baby – Participants crawl through a tunnel filled with a tear-gas-like substance.
- Dead Ringer – Participants use handheld rings to traverse a set of inclined and declined pegs.
- Balls Out – Participants use hanging rope to cross an angled wall.
In January 2016, Tough Mudder unveiled several new obstacles for 2016, including Block Ness Monster, a series of rotating blocks floating in waist-deep water, designed to require teamwork to conquer. This obstacle received the highest participant rating of any obstacle in Tough Mudder history while in testing. Tough Mudder also revealed three new obstacles for 2016 that are exclusive to participants who have completed more than one Tough Mudder event: Backstabber, an inclined wall ascent using pegs; Rain Main, a watery passage underneath a chain-link fence while water drips down; and Frequent Flyers’ Club, a jump from a height onto a crash mat.
Tough Mudder introduced six new obstacles for 2017 season in November 2016. Obstacles include: Augustus Gloop, ascend up a vertical tube with water gushing down; Funky Monkey: The Revolution – an update on the original obstacle with series of revolving wheels to be traversed dangling over water; Arctic Enema: The Rebirth – another update on a classic – slide head first down a tube into icy water and submerge again under a wall to escape; Black Hole – an update on the original Birth Canal obstacle – one must crawl their way through a gauntlet of 100 lb. water-filled barriers in total darkness; The Reach Around – 20 foot wall that one must then go beyond vertical to scale over; and Kong – 30 foot high obstacle that participants swing from ring to ring at increasing further distant like Tarzan. 
In January 2018, Tough Mudder introduced its’ new obstacles for the year which include Kong Infinity and Happy Ending. Kong Infinity is a 15-foot climbing challenge in which participants scale to reach a barrel that they rotate along a set of tracks suspended more than 20 feet off the ground to reach the other side. Happy Ending was invented by the winners of the Tough Mudder Obstacle Design Challenge - Ross Munro and Jonny McDonald of Glasgow, U.K. It is the new finishing obstacle and replaces Electric Shock Therapy. Happy Ending is 25-feet-tall, more than 80 feet wide and 100 feet long and the biggest structure to ever be built by the OCR brand. Participants form a human-pyramid up a slippery 40-degree slope and help each other climb to the top at which they dive feet-first down a 30-foot slide into a pit of water. For an added challenge, participants can opt to use the “Third Rail” on Happy Ending —sliding under wires charged with more than 10,000 volts of electricity over part of the exiting slide portion.
At the April 20, 2013, Tough Mudder Mid-Atlantic event in Gerrardstown, West Virginia, a 28-year-old participant, Avishek Sengupta, died following an incident on the "Walk the Plank" obstacle. Witnesses told Berkeley County sheriff's office, which investigated the death, that he was submerged in water for between five and 15 minutes. A coroner ruled the death an accidental drowning and the sheriff's office concluded it did not warrant criminal charges. This was the first fatality in Tough Mudder’s history.
In 2014, The Atlantic reported on an incident at an October 2012 Tough Mudder event in Beatty, Nevada. There, three military personnel were admitted to the Nellis Air Force Base medical center with vomiting and bloody diarrhea. All had fallen face-first in mud on the Tough Mudder course on a nearby cattle ranch a week before. Subsequent investigations linked 22 cases "most likely caused by infection with the fecally transmitted bacterium Campylobacter coli," possibly from water contaminated by livestock. 
Statements released by Tough Mudder since the incident have discussed the company’s commitment to safety, and Tough Mudder CEO Will Dean has stated that Tough Mudder events are about 20 times safer than triathlons.
According to study by Canadian researchers and published in the Emergency Medicine Journal in 2016, serious injuries are rare at obstacle course races like Tough Mudder. Only about 1 percent of participants are injured during obstacle course races, and most of the injuries are minor and only require first aid. Lead author of the study, Dr. Alana Hawley, of McMaster University in Hamilton, said “The health risks of participating in such obstacle courses are minimal, however, and are comparable to the injury risks at any mass gathering event.” Most of those injured - 89 percent - in the study group of more than 45,000 people participating in eight mud runs returned to the event without needing any further medical care.
In June 2016, Tough Mudder named its new charity partner Team Rubicon, the veteran first responder organization, TEAMRUBICONUSA.org. The goal of the partnerships is to raise awareness of Team Rubicon among Tough Mudder enthusiasts, friends and overall population, drive volunteer registration and activation, and help Team Rubicon in a $1.5 Million charitable raise by the end of 2017. 
Previous charities supported have included Wounded Warrior Project (in the United States) and Wounded Warriors Canada.
In the United States, none of the revenue generated from Tough Mudder admissions sales goes directly to any charity. However, participants are incentivized by the Tough Mudder organization to raise money through their participation in a Tough Mudder event for donation to the Wounded Warrior Project. As of February 2014, Tough Mudder reports that their yearly revenue is approximately $75 million, and that participants have raised around $6.5 million total for the US Wounded Warrior Project since Tough Mudder's inception in 2010.
Tough Mudder has partnerships with many notable companies. In November 2015, Tough Mudder announced Merrell as the presenting partner for Tough Mudder and Tough Mudder Half, in a global multi-year deal. For 2016 it announced additional new North American partners including Old Spice and Microsoft Band, in addition to returning sponsors including Shock Top, U.S. Army, and Cellucor, and Toyo Tires. Additional international partners include Jeep, Virgin Active, Volvic, and Bosch.
Aflac became Tough Mudder’s “Official Supplemental Insurance Provider” in April 2017. As part of the partnership, Aflac and Tough Mudder launched a six-month campaign called the “Aflac Small Business Challenge” to encourage camaraderie and team building among employees of small businesses.
In the same month, Tough Mudder also announced Lucozade, as the company’s Official Sports Drink Sponsor of Tough Mudder's UK events, advertising the partnership on 50 million of its bottles. Jeep also announced as part of its current deal, that they will be producing 100 limited edition Renegade Tough Mudder vehicles for sale only in the UK. Also in the UK, Head & Shoulders became the official hair care partner for Tough Mudder’s 2017 UK events. As part of the deal, Tough Mudder will place the shampoo’s company’s branding on its Augustus Gloop obstacle, create original content together, and offer participants to clean up with Head & Shoulders products at shower stations after the events.
In July 2017, Tough Mudder announced an official partnership with Samsung in the UK. Tough Mudder will deliver exclusive content and training tips to be seen across Samsung devices and offer unique on-site experiences at Tough Mudder's U.K. events. The partnership began this summer and runs through the '18 event season.
In the United States, Amazon became the “official online retailer” for Tough Mudder’s 2017 US events. The brands opened a digital storefront where users will be able to shop for fitness and health products, as well as view videos from Tough Mudder fitness and wellness experts on training, nutrition and health that being is creating solely for Amazon. Also in the US, Guinness Blonde American Lager became the official beer partner for 2017 and will have a beer garden where participants and spectators gather at events.
Tough Mudder announced in November 2017 a new 2018-2019 US official sports drink partner, Kill Cliff. The brand’s endurance and recovery sports beverages will be served both during and after all US based events. In addition, Kill Cliff will serve as the presenting sponsor of the Tough Mudder X Series. The partnership kicked off at the 2017 World’s Toughest Mudder with Kill Cliff being the official sponsor of one of the event’s most infamous obstacles, The Cliff --- a 35-foot cliff jump into Lake Las Vegas.
Fitness drink brand Celsius was named in February as the presenting sponsor for the 2018 Tough Mudder North American Challenge series. The series includes more than 100 events this year including Tough Mudder Half, Full and 5K.As part of the sponsorship the Celsius logo will be featured on Tough Mudder’s Everest obstacle, with drinks handed out before each event. In addition, Celsius is also official sponsor of the Toughest Mudder and World’s toughest Mudder race series, which are televised on CBS. Former presenting sponsor, Merrell, remains as the official shoe sponsor for Tough Mudder. 
In March 2018, Scottish craft beer Brew Dog signed as the official beer partner for all Tough Mudder UK Challenge series events. The brand’s Punk IPA will be handed out to participants after each event.
