Tough Mudder events are hardcore 10-12 mile obstacle courses designed by British Special Forces to test your all around strength, stamina, mental grit, and camaraderie. As the leading company in the booming obstacle course industry, Tough Mudder has already challenged half a million inspiring participants worldwide and raised more than $2 million dollars for the Wounded Warrior Project. But Tough Mudder is more than an event, it’s a way of thinking. By running a Tough Mudder challenge, you’ll unlock a true sense of accomplishment, have a great time, and discover a camaraderie with your fellow participants that’s experienced all too rarely these days.

FACT #1 – Marathon running is boring.
And the only thing more boring than doing a marathon is watching a marathon. Road-running may give you a healthy set of lungs, but will leave you with as much upper body strength as Keira Knightley. At Tough Mudder, we want to test your all-around mettle, not just your ability to run in a straight line, on your own, for hours on end, getting bored out of your mind. Our obstacle courses are designed by British Special Forces to test you in every way and are meant only for truly exceptional all-around people, not for people who have enough time and money to train their knees to run 26 miles.
FACT #2 – Mudders do not take themselves too seriously.
Triathlons, marathons, and other lame-ass mud runs are more stressful than fun. Not Tough Mudder. As hardcore as our courses are, we meet you at the finish line with a beer, a laugh, and a rockin’ live band. It’s pretty hard to take yourself seriously when you’re covered in mud and have just finished an obstacle called ‘Just The Tip’, so please don’t show up at a Tough Mudder without a sense of humor. Just check out the ridiculous team costumes in our event photos to get a feel for the spirit of Tough Mudder.
FACT #3 – You cannot complete a Tough Mudder course alone.
To get through mud, fire, ice-water, and 10,000 volts of electricity you’ll need teammates to pick you up when your spirits dip. To get over 12 foot walls and through underground mud tunnels, you’ll need teammates to give you a boost and a push. Tough Mudders are team players who make sure no one gets left behind. To that end, all Mudders are expected to uphold our ideals and exhibit teamwork and camaraderie both on the course and off it. All participants are asked to join us in reciting the Tough Mudder pledge before starting each event.

Location, Course & Obstacles
Big Mudder is still evaluating venues for this epic event – we do guarantee the venue will be within a 2 hour drive of Los Angeles. TMHQ will email all registered participants when we select a venue.

You will be emailed your assigned start time within a week of the event.
Post Party & Awards
The fun doesn’t stop when you finish the Tough Mudder obstacle course. Big Mudder throws a killer post-party consisting of live music, contests, awards, and of course the carnival of tough. Check out our post party & awards page for more details!
Tough Mudder Tattoos

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.

Event Photos
Brightroom is our official event photographer – they will be taking action shots of you throughout the Tough Mudder course, so make sure your bib number is clearly visible! There will be 3 designated Photo Zones throughout the course – look for the “Photo Zone” signs to ensure your picture is taken! Photos will be available online for viewing and purchasing the week after the event. Can’t wait? We understand: check out some of our previous event photos.
