This is the Meetup group of the Boulder Mountainbike Alliance (BMA). You do not need to be a member of BMA to participate in our rides. 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. BMA hosts many group rides and events that do not appear on this site. Join today!

This Meetup group is for any recreational mountain biker that wants to meet up with people for trail rides around Boulder. There are rides for all skill levels: beginner, intermediate, and maybe even a few advanced. The rides are meant to be fun for all, so those intimidated by more advanced riders, fear not. These are ego-free rides. If you need to get off your bike and walk it up a steep or tricky section, it's OK! We'll try to keep a pace that works for the whole group. Here are some of the trails we frequently ride around Boulder, and a rough guideline regarding their level of difficulty: Betasso - Beginner (easy) Marshal Mesa - Beginner (easy) Dowdy Draw - Beginner/Intermediate (medium) Heil Ranch - Intermediate (hard) Walker Ranch - Intermediate (hard) (you can google these trails for more descriptions of their length and difficulty) Ride details will be posted so you can judge for yourself what fits your skill level. 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!
