In-N-Out Burger® Tough Mudder Challenge

In-N-Out Burger® and Tough Mudder are teaming up for one epic challenge. Join us in Big Bear, CA on September 5-7, 2025 to tackle world-famous obstacles, earn exclusive finisher swag, and experience a finisher feeling that’s never felt (or tasted) so good. Cross the finish line and grab your iconic orange headband, along with a freshly cooked Double-Double® from an In-N-Out Burger Cookout Truck.

5K and 10K distances available. With proceeds directly supporting organizations dedicated to fighting substance abuse and human trafficking in our communities, every mud mile increases in significance by the time you reach the finish line. It takes grit and determination to break free from these chains, and that's why we're taking on Tough Mudder - to show our unwavering support for those battling these challenges and emerging victorious.
