In a one-of-a-kind partnership, California’s favorite family-run burger chain is partnering with Tough Mudder for a uniquely custom event benefiting the Slave 2 Nothing® Foundation – coming to Big Bear, CA September 5-7, 2025

10.11.24, CALIFORNIA: Two iconic brands collide for one incredible event as In-N-Out Burger unveils plans to host a custom Tough Mudder event in September 2025. The globally renowned obstacle course brand has announced today a deal that will see the team facilitate a first-of-its-kind custom event for California’s favorite burger chain.

The event will commence on Friday, September 5, with dedicated racer waves for In-N-Out Associates, friends, and family. In the afternoon of Friday, September 5 through Sunday, September 7, waves of the obstacle course event will be open to the general public with the site at Big Bear Mountain Resort expected to see attendance of more than 15,000 throughout the event weekend.

100% of ticket sales on Friday will benefit the Slave 2 Nothing Foundation. A portion of the proceeds will also benefit the Foundation on Saturday and Sunday. Created by In-N-Out Burger, the Slave 2 Nothing Foundation has a mission to free people from being enslaved to any person or substance. They fulfill this by providing financial support to organizations in eight states and local communities.

Big Bear Mountain Resort will play host to the event that will have 5K and 10K courses with stunning, mountainous scenery and innovative obstacles. Alongside the regular festivities Tough Mudder participants have come to expect, In-N-Out will be enticing participants back to the finish line with free burgers from their on-site cookout trucks while finishers are presented with a custom headband, finisher tee, medal and lanyard. Participants will also have the opportunity to take part in a variety of exclusive brand activations throughout the event village.

Tough Mudder owner and Spartan Race Founder Joe De Sena said: “Tough Mudder is all about overcoming challenges and savoring the reward. We’re thrilled to partner with In-N-Out and Slave 2 Nothing to give back to the community and provide an unmatched on-course and finish line experience – burger and all.”

In-N-Out Burger president and owner Lynsi Snyder-Ellingson said: “My husband Sean and I have completed a Tough Mudder and recognize it takes determination, stamina, strength, and teamwork. Slave 2 Nothing recognizes these same qualities are crucial in tackling the issues of addiction and human trafficking. We’re incredibly thankful for this partnership with Tough Mudder and the opportunity to host such a unique event. Together, we can impact even more lives by helping them find freedom from being enslaved to any person or substance.”
