You’ve got massive Mud footsteps to fill. Meet the legends who left them.

Tough Mudder Legends

Oh yeah, They're legends.

Meet the Mudder legends behind the madness. These vets know the ins and outs (and ups and downs) of training for Tough Mudder. They’re mountain climbers, distance runners and martial artists – in a word, tough. Keep a look out for Weekly Training Tips from these legends on the Tough Mudder blog. In the meantime, they suggest some Boot Camp exercises.

Mustache Man

His mom might call him Andy, but Mudders must call him Mustache Man, Double M for short. If you think that’ll be a problem for you, MM knows a few different forms of martial arts that might change your mind: Jeet Kune Do, Kali, Muay Thai, and Japanese Shoot Wrestling. Never heard of Japanese Shoot Wrestling? Doesn’t matter. What matters is that this man is a real Tough Mudder on and off the course. As a certified personal trainer, MM has been whipping Mudders and MMA competitors into fighting shape for over a decade. If you’re lucky, he might share a few battle stories at the finish line. But, a word of advice: don’t stare at the stache. MM is cool, calm and kind, but the stache? It’s unpredictable.

Nigel Thomas

The Chief Training Officer

Nigel Thomas is Tough Mudder’s Chief Training Officer and advises the Mudder Ship on all things tough. He knows the ins and outs of everything from obstacle designs to our training program. But Nigel won’t dish on what awaits you at your next Mudder Challenge. In fact, he makes his living keeping secrets: Nigel is the CEO of Blue Mountain Group, a specialist security, driving and training company. With 14 years in the British Special Forces under his belt, there’s no one better at making sure Mudders earn that headband. He recently passed his 50th birthday, but if you want to wish him a happy birthday, you’ll have to climb Mt. Everest to find him. That’s not a joke. Nigel’s idea of a party is climbing a mountain. If you’re a first time Mudder, you’ve got a trek ahead of you, but at least there’s someone to look up to.

The Shark

The Shark swims in muddy deep waters. A 42-year-old mother of two, Juliana is the female winner of the inaugural World’s Toughest Mudder (2011) and an extreme endurance and plant-based athlete. She’s been competing in triathlons for 23 years, and is one of the leading obstacle-endurance athletes in the world. Her energy is mental as much as it is physical. The Shark is a voracious reader who wades into the waters of philosophy and spirituality to fortify her unstoppable mental Mudder game. For Juliana, the real meaning of grit is biting back when life gets tough by supporting and depending on the people around her. A yoga practitioner and certified USA Triathlon Coach, The Shark lives by the credo that mud is a journey, not a destination.
