Good quality trails don’t magically appear, trails happen because COMBA and our dedicated members and volunteers all help to make them happen.


Building, protecting and maintaining the trails we all enjoy is just some of the necessary work that we do. Without you, trails fall into disrepair, or worse, don't get built at all. Our access is never guaranteed. It’s mountain bikers like you and our local organization that champion new trails.


Some recent and upcoming trails projects that your membership $'s help fund:
  • Warren Gulch is NOW BACK OPEN! This popular shuttle-run has been closed for two years due to private property conflicts. 

  • North Elk Creek has a new trail called Rusty Buckle that cuts over a peak from NEC to Borderline, OPEN NOW!

  • Maryland Mountain’s new expert trail is called Ore Chute and it is steep and rocky! Full trail opened in September of 2022.

  • Virginia Canyon Mountain Park trail system has it’s main “spine” trail open now as a hiking-only trail until the bike trails are built. The first bike-only descending trail is funded and we are moving towards a fall build.

  • There’s a new bike-only directional trail coming soon to Lair Of The Bear! This will allow riders to descend on a designated use trail designed and built for mountain biking, safely away from the busy lower section and the path along the creek. This project was a COMBA trails project submittal in 2018 and we’re stoked to see it coming to JCOS! The trail has been designed by JCOS and is currently out to bid for construction. More news soon!

COMBA's work of late has been absolutely amazing. Floyd Hill is superb.  Maryland Mountain is even better. The trail connecting Staunton and Cub Creek is super interesting and fun. You guys just keep going with the hits!!  My props to everyone involved in the advocacy and trail-building work for COMBA.  


My hat is off to you and everyone involved. You listened to the will of the riders and delivered in a big way! I'm still buzzing from riding it yesterday!


COMBA is the best thing to happen to all trail users in Colorado! Building trails and trying to keep trail conflicts at a minimum. Given how many out-of-staters have invaded, you’re vitally important in helping to preserve our lifestyle!! Just re-upped for another year - just a tad more than a full-day lift ticket at Vail. Worth it!

*Membership and donation fees are tax deductible!



For a helluva lot less than a lift ticket, you can help build more great places to ride on the Front Range. We have an awesome slate of bike-focused new trails on tap that need your support!


Adding your voice to our ask for bike-optimized or bike-only, directional trails wherever possible.


Helping to educate new riders and trail users on how to get the best experience out of their Front Range trails.

Our members make our work possible! COMBA is a membership funded 501(c)(3) non-profit organization. Your membership dollars build and maintain trails, host events and rides, encourage youth to get outside on bikes, and represent mountain bikers at the local, state and federal level. You'll reap the benefits of your investment every time you ride.

We know it's easy to think that trails are already funded with our tax dollars, but when we dream of bike-specific, challenging and directional trails, we often exceed the scope of what our land agency partners have in their budget or plans. So we put our money where our mouth is, stepping up to raise funds to get these sweet trails built. This means that we get to work together as a community to create awesome places to ride. Win-win! And as each rider joins us, the financial cost is reduced when we all share it. For comparison, joining is much cheaper than buying a lift ticket or eighteen holes of golf — and it results in local assets we all enjoy for years to come. 

Some of the great projects we're doing with membership dollars include new, bike-only downhill trails at Floyd Hill, Maryland Mountain and Virginia Canyon. This increase in bike-only, directional trails is a direct result of the advocacy we're able to do through your support. Thank you!
