Post Party:

You just conquered 10-12 miles of Big Mudder’s wrath – the only obstacle between you and the finish line is Electroshock Therapy. You pause to gather your cojones, then try to run through the live wires without getting shocked (impossible). You get repeatedly zapped with 10,000 volts of electricity, and it does NOT tickle. After dropping your fair share of f-bombs, you cross the finish line. You’re greeted with an orange headband, a high-five and a hard earned beer.
You have just completed Tough Mudder, and you are among the elite group who have the honor of saying they’ve conquered probably the toughest event on the plantet. What do you do next…?

At most events, Tough Mudder will be offering tattoos of our bad-ass logo to all finishers who want to commemorate their epic achievement. Once you get inked, fill out a tattoo registration entry form to get free entry into a Tough Mudder event of your choice! Please note: some venues don’t allow tattoos on-site. If this is the case, we encourage participants to get Tough Mudder tattoos at local tattoo parlors.

Tough Mudder is a proud supporter of the Wounded Warrior Project. To date, Tough Mudder participants have raised approximately $6.5 million to support thousands of warriors returning from the battlefield. Every dollar raised is well spent: Providing combat stress recovery programs, Adaptive sports programs, Benefits counseling, and Employment services. And these are only a few examples of the programs offered to our injured veterans! These programs and services aid in brave Americans’ transition from service-connected injury to civilian life. We host a team of Wounded Warriors in every Tough Mudder event, just to remind everyone what the definition of the word ‘bad-ass’ really means. Look for participants carrying the Wounded Warrior Project flag at our events!

Tough Mudder is not a race. A Tough Mudder event is a personal challenge — the goal is simply to complete the course. This is why we do not time people and why we try to avoid using the word ‘race’ when describing our events. This is a critical tenet of our philosophy and our pledge.

Because TMHQ has received inquiries asking whether or not women can participate, we would like to make it clear that women are strongly encouraged to register, and that 25% of all registrants are female.

Tough Mudder events are designed to test all round fitness. However, fitness alone will not get you round the course. You will also need mental endurance to complete the course and overcome the obstacles. You will need to train beforehand

Tough Mudder recommends that all participants possess basic swimming fundamentals and be skilled to not only tread water but also prepared t swim a minimum distance of 25-30 feet. Also, we suggest that persons with limited swimming ability to bypass the deep water parts of the course, as basic swimming skills are essential for the safe completion of these obstacles.

Tough Mudder is not supposed to be about getting a faster time than your buddy, so it’s fine by us if you want to skip an obstacle. The way we see it, you are there to have fun and get a real sense of achievement at the end. If you think a particular obstacle isn’t going to do this for you, just go around it – no shame there. However, if you are skipping an obstacle just to improve your time, then we think you are only cheating yourself. You paid to do the course – why not actually do it? Obviously, though, for some who participate there is a real element of competition involved in the event, so we do say that to qualify for a winners’s prize or for the World’s Toughest Mudder competition you must have completed all the obstacles.

For health & safety reasons, you are not allowed to bring your pets to Tough Mudder.

All participants will have the opportunity to be hosed down by volunteer firemen after finishing the course. At some venues, there will also be a shower option available.

What to wear to a Tough Mudder?
Shoes – normal running shoes. Cleats won’t help – in fact they’ll be worse on your feet and are dangerous for the other participants.
Clothes – lightweight stuff that dries quickly. Even if it’s a cold day, heavy or thick clothing will just retain water and make you colder. You should also bring a change of clothes for after the event so you can enjoy the post party.
Gloves – this one is more debatable. Some people swear by them, others prefer to go glove-less (faster drying). If you go with gloves, be sure to grab tough, thick ones to prevent burns from the ropes and splinters from the walls.
A watch – if you care about knowing your time. It’s on you to time yourself.
Photo ID – You MUST bring a photo ID. We cannot stress this enough.
Copy of your confirmation email.

Join our team of Tough Mudder Volunteers (MVPs) and create a life-changing experience for yourself and others. As an added bonus, all MVPs get up to 90% off (yes, that’s right) a future Tough Mudder.

Are the 10-12 mile Tough Mudder® courses somehow not enough for you? World’s Toughest Mudder is the culminating event of the Tough Mudder calendar and takes the concept of being a Tough Mudder to a whole new level. This extreme competition puts the world’s most hardcore Mudders℠ through a grueling 24-hour challenge designed to find the toughest man, woman, and 4-person team on the planet.
If you’re crazy enough to think that 24 hours of torture sounds like fun, then you’re eligible.
Previously, we’ve asked people to qualify by submitting their times from a Tough Mudder during the season. But the fact is that this year, you’re not going to be competing on a normal Tough Mudder course – we’re going to be feeding you something even more intense, with more obstacles per mile. So how fast you can run isn’t as important – what really matters is how much pain you can push through.
