About BMA
The mission of BMA is to serve as a positive voice for mountain biking in the greater Boulder Colorado area by improving the trail experience for all users through social rides and events, advocacy, and trail building. Join BMA (https://www.imba.com/join/chapter/bma) today to support our efforts!

This group hosts weekly group mountain bike rides for those who want to explore the MTB trails around Boulder with others at their level. The rides are meant to be fun for all, so those intimidated by more advanced riders, fear not. If you need to get off your bike and walk it up a steep or tricky section, it's OK! We try to keep a pace that works for the whole group. All our rides have a Ride Guide, and many also have a sweep and are "no-drop" rides.

Our weekly rides:
Tuesday - GurlzRide (beginner, intermediate)
Wednesday - Knobby Wednesday (beginner)
Thursday - Trails & Ale (intermediate, advanced-intermediate)

Looking to improve your riding? We also offer MTB Skills Clinics for all levels.
Find out more about skills clinics.

Want to get involved? We are an all volunteer organization and are always looking for enthusiastic people to lead rides, volunteer at events, help with admin, participate on a committee etc. Email us at volunteer@bouldermountainbike.org to get involved.

Here are some of the trails we frequently ride around Boulder: Betasso, Marshal Mesa, Dowdy Draw, Heil Ranch, Walker Ranch, and Magnolia. You can find more information about these and other local trails on the on MTBProject (https://www.mtbproject.com/directory/8007420/boulder), which has an excellent breakdown of trail lengths, technical difficulty, elevation gain, etc.

Please arrive a few minutes before the posted time of the ride. If it says the ride is at 6pm, then that's when we start peddling. Looking forward to seeing you on the trail!

Trails & Ales

West Magnolia - Magnolia Road trailhead

This intermediate level ride is a great mid-week tonic. Ride at your own pace and we’ll regroup at intersections. We finish every ride by gathering at a local establishment for food and good cheer. Explore trails that are new to you and find a new riding buddy or two. Join the fun! This week we'll ride East Magnolia's Dot Trails. The Dots are rocky and rooty and there's a decent climb and a small hike-a-bike section to the high-point. With very little signage and lots of intersections, this is a great area to get a guided tour. Aerobic Difficulty: 6/10 Technical Difficulty: 7/10 Please consider carpooling from the Justice Center and leave extra time for the construction in Boulder Canyon!

Gurlz Ride

Walker Ranch Loop Trailhead Parking Lot

Ladies, come on out for our fun rides and post-ride get-togethers! We love to ride and enjoy meeting other women who do too. We also support each other as we progress in our bike skills. At the trailhead, we split into two groups: beginner and intermediate/advanced. Our beginner ride has a sweep so you won’t get dropped. Join us! Walker Ranch is an advanced riding area. There's a mix of fast flowy singletrack, technical rocky sections, and even a somewhat difficult hike-a-bike section. It's never flat, and some of the climbs are quite steep.

Knobby Wednesday - Beginner Ride

Heil Valley Ranch

Join the fun on mountain bikes! These Knobby Wednesday entry-level rides for beginner riders will give you a chance to practice your skills, have fun, and be safe riding trails. Before each ride we will review fundamental tips about riding, then we will head out on an entry-level trail ride. This is a family-friendly ride with two Ride Guides so nobody will get left behind. Overland Loop is all singletrack, all the time. Some fun "whoopdies" and some "swoops" and probably a "thingamajig" or two! The trail is only about 2 miles long and packs a lot of great beginner (and even some green-blue) level features. We'll loop this trail a few times, and also check out the new Schoolhouse Loop and skills area. Aerobic Difficulty: 3/10 Technical Difficulty: 3.5/10 IMPORTANT INFO ABOUT THE RIDE - Riders must sign a liability waiver once during the season.

Farewell to Jason Vogel Ride, Happy Hour and Shenanigans

West Magnolia - Magnolia Road trailhead

Long-time BMA board member Jason Vogel is leaving Boulder for the greener pastures of Seattle. We asked him if we could hold a happy hour send off and he insisted that it be held in the woods where he can take some of you all out to experience some #SeldomSeenSingleTrack in the Nederland area. If you are interested in helping send Jason off and maybe learn about a new trail in the process, come on out for a ride at 3pm, beers at 5:30, or stay and roast some s'mores over a campfire overnight if you want to camp. Meet up at the main parking lot at West Mag. Yes, we know it's a Monday but it's going to be worth it. You should leave work early and #rideyourbike. This will be an intermediate/advanced ride. If you haven't ridden with Jason, be prepared to get "Vogeled."* Please consider carpooling from the Justice Center and leave extra time for the construction in Boulder Canyon!

But you will ride trails you've never seen before and it will be worth it.
