These aren’t just medals. They’re your proof that you signed up to get soaked, shocked, and thoroughly humbled… and somehow loved every second of it. For 2026, meet The Hex System: a slick new way to show off your story, one course at a time. Every event gives you a Hex that snaps right into the middle of your medal. A mud-splattered memento of all the ridiculous stuff you did, the kind most people would run a mile from. Keep reading to find out what you’ll earn on each course.
5K Medal
Cross the line, receive your 5K medal, and claim your orange 5K Hex, the first step in a one-in-three challenge known as the Tough Mudder Trifecta. Proof you turned up, got muddy, and realised you kind of enjoyed it.

15K Medal
The 15K medal marks a big step up: more obstacles, more distance, and a serious test of endurance. It’s built for those ready to go beyond the basics and prove they can take on the full Tough Mudder challenge. By completing the 15K distance, you achieve the medal, plus a 15 distance hex: the second step in your Trifecta conquest.

The Reverse of the Medal
Flip it over to see a hidden design, plus a bonus Hex coin for both the 5K and 15K medals. Because if you’re going through it, you deserve something shiny on both sides.

Infinity Medal & Buckle
The Infinity medals are built for those who go beyond. Each one marks the distance you’ve conquered throughout the day, every lap, every muddy kilometre, every moment you chose to keep moving. Hit the 30K mark (or 20K for Adaptive Athletes) and you’ll earn your Infinity distance hex that shows just how far you’ve pushed. Reach 50K and you’ll unlock the Infinity Buckle, a symbol of serious mileage and even more serious determination.


The Trifecta
Complete the 5K, 15K, and Infinity in a single season to unlock the coveted Trifecta Medal: a brand-new accolade that nods to your year in the mud and proves you’ve taken on every distance and lived to tell the tale.
