Tough Mudder

Mark Your Calendar for Big Bear Tough Mudder coming September 2025 – with a delicious surprise!

Big Bear Lake’s first Tough Mudder this September 2025 is a delicious event serving up challenging terrain, mud, demanding obstacles, mud, epic views, and mud, teamwork, camaraderie, more mud, and finally…

This exclusive co-branded In-N-Out Burger® Tough Mudder Challenge offers a 5K and 10K course. Crossing the finish line not only tastes so good but makes the world a better place. Proceeds directly benefit the Slave 2 Nothing Foundation that is dedicated to ending substance abuse and human trafficking. The 5K and 10K course races are offered Friday, Saturday, and Sunday. Also, enjoy the oh-so-delicious Mudder Village Festival with Double-Doubles® served hot and fresh by In-N-Out® Cookout Trucks.

THE VENUE

Rally your crew, Big Bear. In-N-Out Burger is serving up a challenge you cannot afford to miss (think: FOMO like you’ve never felt before). Prepare to tackle a customized 5K or 10K Tough Mudder course, complete with a (secret) obstacle menu, epic views, unforgettable teamwork moments, exclusive co-branded swag and a finisher feeling that’s never felt (or tasted) so good. With proceeds directly benefiting the Slave 2 Nothing® Foundation which is dedicated to fighting substance abuse and human trafficking in our communities, every muddy mile has a meaning. And after you’ve conquered the course, celebrate in our Mudder Village Festival with an iconic Double-Double®, made fresh from one of In-N-Out Burger®’s Cookout Trucks.
