About the Event

Join us at Beautiful Arroyo Vista Community Park in Moorpark for the 13th Annual Mammoth Run!

Whether you're an experienced runner chasing a personal best or simply looking for a fun morning with family and friends, there's an event for everyone. Our 5K and 10K races feature a mostly flat, fast course that is ideal for runners of all abilities and offers an excellent opportunity to achieve a new personal record. Please note, there is a discount for runners 18 and younger.

For families and casual participants, we also offer a 1-Mile fun Run/Walk, making this a great community event for all ages.

Conveniently located next to Moorpark High School (see address below), Arroyo Vista Community Park provides the perfect setting for a fun-filled morning. Participants will enjoy music, warn-up stretches, giveaways, and a festive atmosphere throughout the event.

Medals will be presented to top finishers in each division, and the first 100 finishers will receive a commemorative participation ribbon.

Every registered participant will receive:

A goodie bag
A free moisture-wicking athletic T-shirt (guaranteed for registrations received at least 2 1/2 weeks before the event)
One complimentary raffle ticket for a chance to win great prizes

Proceeds from the 13th Annual Mammoth Run benefit local charitable organizations, including the Food Pantry, the Boys & Girls Club, and The Rotary Foundation's ongoing mission to eradicate polio worldwide.
