What we're about

This is the Meetup group of the Boulder Mountainbike Alliance (BMA). We have 3 group rides every week for riders of all levels. Rides are open to everyone (members and non-members). Find out more (https://bouldermountainbike.org/) about BMA.

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!

Gurlz Ride

Needs a location

This week we will be riding at Betasso Preserve, an intermediate riding area. Expect flowing single track that is mostly easy, with some small embedded rocks and rooty areas, and few stiff pitches. Some trails are fairly narrow with exposure and may not be suitable for beginners. The full figure 8 route of both loops is a bit under 7 miles and 800 ft of elevation gain. Extra Benjamin loops can add to the fun and mileage.

Aerobic Difficulty: 5/10
Technical Difficulty: 4/10

Trails & Ale

Needs a location

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.

Aerobic Difficulty: 8/10
Technical Difficulty: 8/10

ABOUT TRAILS & ALE
This intermediate/advanced level ride is a great mid-week tonic. Ride at your own pace and we’ll regroup at intersections. Explore trails that are new to you and find a new riding buddy or two. We'll plan to tailgate together at the end of the ride or go to a restaurant, see comments for picnicking details.
