Summit County Mountain Bike Alliance

SCoMBA is the Summit County chapter of the International Mountain Bicycling Association, or IMBA. SCoMBA is the successor organization of the Summit Fat Tire Society (SFTS), which was founded over 30 years ago.

We have helped build, re-route and maintain numerous trails over the years, including: Aqueduct Trail, Aspen Alley, Blair Witch, B-Line/Barney Flow, Colorado Trail, Gifford Pinchot, Groovy Uvi, Keystone Landfill Trails, Lenewee Trail, Peaks Trail, Ptarmigan Trail, Snake River Bluffs, Soda Ridge Trail, and the Tenderfoot Trail System. 

We also offer events such as trail work days, mountain bike skills clinics, and social events such as our season kickoff party. In 2022, we hosted our first ever winter mountain bike downhill race at Arapahoe Basin called Slush N' Spokes. It was such a great hit, that we brought it back in 2023 and continue to host it each year. The 2025 race was a blast! 

WHAT HAS SCoMBA BEEN UP TO?

Over the last several years, SCoMBA’s Board began to realize that its path to continued success lay in hiring an Executive Director. They successfully completed this last fall, with our new Executive Director starting about a year ago. In July 2024, we added 4 new Board members, some of whom have significant non-profit experience with Friends of Dillon Ranger District. We also elected a new President, Treasurer, and Secretary from among our Board Members. The newly expanded board and officers have put in hundreds of volunteer hours since then and continue to work tirelessly to help us meet our goals by overseeing committees, training new volunteers, and more. 

2025-2026 PROJECTS

We are thankful that we were able to make progress on multiple projects during the 2025 season. We recently completed phase 1 of building 2.5 miles of trail reroutes on the Soda Creek Trail, which will make it significantly more sustainable. This project will continue into 2026. SCoMBA worked with the US Forest Service and McGill Trails to complete a rebuild of Broken Wheel Trail, a huge step for progressive trail building in the county. We rebuilt a key bridge on the Aqueduct Trail and removed old materials. 

SCoMBA was able to reroute some worn areas of Blair Witch Trail with the help of RMU and VNTR birds. We also adopted section 6.3 of the Colorado Trail, where we completed a few volunteer days of clearing down trees and drainage. This fall, SCoMBA helped sponsor the Silverthorne Elementary School Outdoor Education Program- supporting both the 5th grade trail building class and 3rd grade bike tech class.

We are very excited to move into the planning phase of building Bobsled Trail, a new blue flow trail, in Tenderfoot Meadows- after recently receiving the support of Summit County Trails and Open Space. 

This coming summer we are also working towards launching a Trail Crew Lead program in order to have 5-8 reliable trail volunteers through our 2026 trail season. This program will involve training these volunteers on proper trail building techniques, pursuing leadership education, and obtaining a Wilderness First Aid certification in order to lead projects in future seasons. 

THANK YOU FOR YOUR CONTINUED SUPPORT

SCoMBA needs your support to continue the work needed to obtain funding, meet with our land managers and area partners, and to build and maintain world class trails in our county. The amount of work we can accomplish depends on our donations, memberships and our success obtaining grants. To complete our work on new trails and maintenance projects we are looking to secure over $200,000 in grant funding before the 2026 season. 

Your continued support helps us have a collective voice when pursuing these projects. Thank you for supporting the trails that matter to YOU!
