Every volunteer matters. Every hour helps.

Boulder Mountainbike Alliance needs your help, and we'll make sure you have fun helping us. After over 20 years of advocating for trails, BMA has learned that great communities build great trails, and great trails build great communities.

We have volunteer roles to fit all types of personalities, interests, time commitments, and experience levels.

Volunteer at our Rides & Events

Whether you've been riding since the Repack days or just started mountain biking, we'd love for you to make your own mark on BMA, and have fun doing it. We need Ride Guides, photographers, trail work greeters & feeders, and lots more!

Volunteer for Trail Building Days

From April 22 to August 24 2014, you can win prizes for giving a little love to the trails you love... 
Sign up for Trail Building and Dig to Win!

In 2013, volunteers donated 2500+ volunteer hours to build, maintain & patrol the trails in Boulder County. If we all help on just ONE trail build day this year we can easily double that amount to 5000 trail building and maintenence in 2014! All ages, experience and fitness levels are welcome. Bring the family out and do your ONE for the trails you love. You just need a willingness to spend a few hours getting dirty in the woods with a bunch of fun people.


If you find a task not listed here that strikes your fancy, or have an even better idea on how you can help, email the volunteer coordinator.
