THE VENUE

Be one of 15,000 Mudders to prove you're tough enough to conquer probably our most technically difficult obstacle course on the calendar. Well-known for being one of our hilliest events of the season, the course route will take you through forest trails, muddy ditches and up to 551m of elevation. That finisher beer will never taste more worthwhile.

WHAT YOU GET

FINISHER AWARD

Boasting a striking new design for 2025, these are not your everyday finisher medals. Symbolic of every drop of sweat, every splash of mud, and every hilarious (and humbling) face-plant, each piece of hard-earned hardware is carefully curated to celebrate your grueling yet gratifying feat.

Finisher Shirt

The harsh reality of having a favourite shirt is that it’s usually the garment that suffers the most abuse. Whether you’ve dragged it through the mud one too many times or prematurely cut the sleeves off, chances are you miss the luster of when it was crisp and new. Cross the finish line in 2025 to earn your Tough Mudder finisher tee.

Finisher Headband

Each iconic orange headband symbolizes a badge of honor – crowned upon only the toughest of Mudders – for overcoming intense obstacles, exhibiting extreme mental stamina, and demonstrating unrivaled teamwork & camaraderie. Cross the finish line in 2025 to earn yours.

Finisher Drink

Cross the finish line and grab yourself some hard earned refreshment. You’ve worked hard, celebrate harder.
