About this race

Folks, it's that time again! Ever fantasized about having a state park as your personal playground after hours? Well, dream no more! Your amazing friends at Dusty Bottoms are making it happen on May 30th at Dos Rios State Park, just outside of Modesto.

When the regular park visitors pack up and go home, that's when the fun begins! Choose your trail adventure: a spicy 3-mile sprint or a robust 5-mile ramble. Both distances are run on buffed out fire roads and will take you by the lovely Tuolomne River.

After conquering the trails, we'll do what Dusty Bottoms does best - hang out, swap stories, and celebrate like the trail champions we are. It's a classic "fat ass" event where every donation helps our park ranger friends keep this slice of wilderness awesome for years to come.

So grab your running shoes, fill those coolers and let's turn this park into our personal after-hours playground!
