Dear Community Partner,

The Rotary Clubs of Moorpark and Simi Sunset invite you to become a sponsor of the 13th Annual Mammoth Run on Sunday, October 4, 2026, at Arroyo Vista Park in Moorpark.

This family-friendly event features a 5K, 10K, and one-mile fun run/walk, bringing together runners, families, local businesses, and community members for a morning of fitness and fun. Proceeds will support local charitable programs and the Rotary Foundation.

Sponsorship opportunities are available at several levels, ranging from in-kind donations to our Platinum Sponsorship, which includes registration for up to 10 runners. Sponsorship is a wonderful way to promote your business or organization while helping Rotary make a meaningful difference in our community.

Please review the attached sponsorship form for information about the available levels and benefits. We would be honored to have you join us as a sponsor of this year’s Mammoth Run.

If you have any questions, please feel free to contact us. Thank you for considering this opportunity to support our community!

Warm regards,

Mammoth Run Committee
