Volunteer for the 2026 Dirt Fondo

Be Part of the 2026 Dirt Fondo Event Team

As we get ready to put on the 14th Annual MCBC Dirt Fondo, we also need volunteers – like you!

On a day when riders will cover up to 43 miles, it’s up to our amazing MCBC volunteer team to mark the route, lead and sweep to keep riders on the course, keep riders hydrated and pumped up at rest stations, and make sure everyone has enough to eat and drink at the celebratory post-ride meal. Whether you have a loved one the route, or you just feel like helping us put on a great event, we’d love your support. 

You’ll receive the coveted MCBC t-shirt, free lunch and a drink, and a ton of gratitude for helping us put on one of our biggest events of the year.

Please fill out the form below and contact info@marinbike.org with any questions. Thank you!
