BLOCKNESS MONSTER GETS A GRENADE BLAST
Tough Mudder isn’t just a challenge—it’s a test of grit, endurance, and pure determination. You push through the mud, tackle the obstacles, and prove to yourself (and the haters) that limits are meant to be broken. And now, we’ve got the perfect partner to help you power through every step of the course.
We’re pleased to announce Grenade as the Official Nutrition Partner for all Tough Mudder UK events in 2025.
Grenade, the UK’s no.1 protein bar brand, is bringing its game-changing energy to the muddiest, toughest courses around.
Plus, it’s big. It’s brutal. It’s back—and now it’s powered by Grenade. One of Tough Mudder’s most legendary obstacles, Blockness Monster, is getting a next-level energy injection. With Grenade in the mix, this fan-favourite challenge is set to be even more epic.
LOCKED, LOADED AND READY TO MUD

When you’re knee-deep in the challenge, you need serious fuel to keep moving. That’s where Grenade’s high-protein, low-sugar bars come in. With 20g of protein, just 2g of sugar, and under 250 calories, they’re the perfect blast to keep you crushing every obstacle.
Expect two Grenade Bar stations out on the course, delivering that much-needed hit of energy when you need it most. And when you finally brave Electroshock Therapy to cross that finish line, a Grenade protein charge will be waiting to help you recover like a champ. Visit Grenade in the Mudder Village to sample the range of Sports Nutrition Powders, including Protein, Pre-Workout and BCAA. Plus keep a look out for some more surprises throughout the season.
