Renowned for its epic Obstacle Innovation Lab, Tough Mudder Inc., has announced its revolutionary twist on obstacles for next year’s season. 2019 will bring 10 new or updated obstacles for every Tough Mudder Classic course, giving Mudders all over the UK fresh ways to challenge themselves and their team.

Tough Mudder fans will no doubt be excited to learn that Mudderhorn is the tallest obstacle to ever appear on a course to date, standing at a staggering 25 feet tall. This colossal climb will test Mudders’ teamwork as they come face to face with their fear of heights and clamber up the cargo net to the top.

Challenging the jaw-dropping heights of Mudderhorn is The Gauntlet, the longest obstacle to ever feature. The Gauntlet boasts multiple sections, each designed to test a different skill set, making it the ultimate total body strength challenge. From balance and agility through to core and grip strength, the Gauntlet will be one of the most demanding obstacles ever seen in the UK.

Meanwhile, Black Widow is set to be a new fan favourite based on rave reviews by early obstacle testers, where agility and teamwork are vital to negotiating and traversing a tangled spider’s web of interwoven tightropes.

Overall, the 2019 Tough Mudder Classic course offers participants twice as much electricity, 1 million litres of water, 3,000 cubic metres of mud, 125 feet of climbing elevation and more than 150 meters traversed above ground.

Every year, new obstacle concepts are submitted by both the public and TMHQ staff, before being examined in Tough Mudder’s Obstacle Innovation Lab. In 2018, over 500 new obstacle concepts were received, with just 50 making the cut to be tested live on courses during an “Alpha Testing” phase.

A secondary stage of trials took place in September, during a “Beta Testing” phase held in London. Here a select group of obstacle testers, along with the newly recruited Chief Obstacle Tester, took on 35 brand new concepts and participated in a series of feedback sessions. After a final round of testing held in Atlanta, the final 10 new or updated obstacles were selected.

Next year, three of these new obstacles will also feature on the shorter 5K courses, bringing the total number of obstacles at a Tough Mudder 5K to 13. These events are designed to encourage fun, teamwork and camaraderie, allowing Mudders of all abilities even more fun ways to slip, slide and scale their way around the course.

“For 2019 we were determined to increase our Obstacle Innovation more than ever before, so doubled our investment into this area. We focused on developing a suite of new obstacles that test our Mudders in unique new ways, whilst encouraging teamwork and camaraderie” said Rachel Norris, International Product & Innovation.

“We’ve spent months planning, scheming, Alpha testing, Beta testing, and even hiring our first-ever Chief Obstacle Tester, and now, our 2019 obstacles are finally here. By unveiling the tallest and longest obstacles ever, along with some more mental challenges with added electricity, we’re confident Mudders will be put through their paces yet again in 2019.”

“We are look forward to welcoming thousands of new and returning participants to Mudder Nation in 2019 to take on our exciting new obstacle menu. As a global tribe, Tough Mudder is committed to connecting people from all walks of life and encouraging them to work together to overcome our best-in-class obstacles. And now, with Tough Mudder 5K coming to every venue around the UK, we are looking forward to welcoming even more Brits into Mudder Nation.” said Will Dean, Tough Mudder, Inc. CEO and Co-Founder.

2019 New & Updated Obstacles:


Always wondered what Tough Mudder looks like from 25′ in the air? Introducing Mudderhorn. This colossal climb is the tallest obstacle ever seen on any Tough Mudder course in the UK. Use teamwork to reach the net, but don’t let the vertigo drag you back down. Victory is at the top, and every Mudder is invited.

The Gauntlet

The Gauntlet is Tough Mudder’s version of a greatest hits album – multiple iconic sections, each testing a different aspect of toughness. It’s where good Mudders find greatness and only the strongest will succeed. Clocking in at over 100’, this isn’t just the longest obstacle of the 2019 TMHQ season – it’s the longest obstacle we’ve built. Ever.

Black Widow

You’ll be wishing you had four extra limbs when you face this web of tightropes suspended over a water pit. Grab on where ever you can and hold on tight as the movement of your fellow Mudders causes you to shake, rattle and roll. Tough Mudder Top Tip: This was the highest rated obstacle at Beta Testing, work on your core so that you can handle the side-splitting laughter.

Augustus Gloop 2.0

Back by popular demand this fan-favourite has been updated to be tougher and even more fun. How do you make this claustrophobic climb trickier? Add more water. You won’t just be clambering up the tubes of yesteryear either, we’ve updated the ascent with three different types of climb. Variety is the spice of life, right?

Leap of Faith

Sometimes, overcoming an obstacle is all about faith. And you better have faith (in yourself) if you’re going to conquer this monumental obstacle (and stay dry in the process). Run, jump and commit to clearing a 6’ water-filled gap, then grab tight to the hanging rope net and don’t let go. You’re only halfway home. Physical strength, mental bravery and the encouragement of Mudder Nation will see you through.


Always fancied yourself as a bit of an action hero? It’s time to embrace your inner Lara Croft as you traverse a 30’ space zig-zagged with electrical wires, that gets increasingly narrow. Bend and contort your body to avoid the wires otherwise, there’s only one destination – welcome to Shocksville.

Tight Squeeze

It’s time to get down and dirty in the smallest space you can imagine. Don’t let claustrophobia get the better of you as you sink into the mud and drag yourself (and your teammates) through a gap that’s tighter than a tube during rush hour.


If you don’t like water and small spaces look away now. In 2018 the test version of this obstacle had Mudders facing their most primal fears. In 2019 it’s back as a permanent feature and of course, we’ve upped the ante. Enter the water pit where you’ll be faced by multiple semi-submerged pipes. Hold your breath, slip under the surface and squeeze beneath the obstruction. Desperate to gasp for air? You’ll be forced to stay low and close to the water by netting that covers the entire obstacle.

Spread Eagle

Like Mudders on toast, it’s time to spread yourself. You’ve got to drop down on all fours and climb like your Mudder credentials depend on it. Because 30’ of quivering, quaking, non-stop shaking slackline isn’t going to let you off easy. Core strength is key, but teamwork rules this obstacle. Lose your balance and you won’t just go down – you’ll take your fellow Mudders with you.

Texas Hold’em

Forget keeping your cards close to your chest, this obstacle demands teamwork and cooperation. To conquer this see-sawing triangular platform you’ll need to choose a Mudder teammate who can hold your hand and have your back. Trust them to bear your weight, engage your core and shimmy your way to success.
