Machete Trail Madness 100k

This Riverside County event features two distinct course experiences, designed intentionally for safety, flow, and participation.

🏁 The Riverside K9 Run Experience (5K)

The 5K Run & Walk is a longer distance course open to participants with or without dogs and is best suited for high-energy dogs and participants looking for more of a challenge. Educational signage along the route highlights shelter facts, stories, and initiatives, creating a meaningful Learn While You Run/Walk experience.

🐕 Mary S. Roberts "Walk With Animals" Experience (2.5K)

The Walk With the Animals follows a separate 1.5-mile, dog-friendly course, created specifically for the safety and comfort of dogs and walkers. Participation in this walk recommends a personal dog or an on-site day foster provided by Mary S. Roberts Pet Adoption Center. This ensures a controlled, positive environment for all animals involved.

🎉 Finish Line Festival & 🍺Beer Garden

After completing either course, participants are invited to enjoy a festival-style finish line experience featuring food trucks, vendors, live entertainment, K9 demonstrations, and adoption opportunities.

Guests 21+ can also access the on-site Beer Garden, offering top-quality draft beer from local and national breweries. The beer garden includes shelter trivia and interactive activations, allowing guests to engage with the mission while enjoying the celebration.

A portion of all proceeds from the event directly supports Mary S. Roberts Pet Adoption Center, helping provide food, medical care, and resources for animals in our community.
