Trail Building

Dig to Win

Join us Thursday October 16 at Full Cycle Bike Shop!
We'll have pizza and Oskar Blues beer.
At the party we'll draw entries and announce the winners of the Dig to Win drawing!
You do not need to be present to win!

Volunteer at least ONE day to help build trails, and be entered to win sweet prizes!

In 2013, volunteers donated 2,500+ volunteer hours to build, maintain & patrol the trails in Boulder County. If we all help on just ONE trail build day this year we can easily double that amount to 5,000 trail building and maintenence hours in 2014!

Trail building is a fun way to create a sliver of trail that'll give you pride every time you ride. With experienced and friendly Crew Leaders at your side, and a nice lunch, fizzy beverages, and good conversation to end the day, it's fun for all.

This April through September, 2014, win prizes for giving a back to the trails... All ages, experience, and fitness levels are welcome. The only requirement? Willingness to get dirty!

What can you win?

  • Niner mountain bike frame
  • Gift cards to local bike shops
  • Schwag from UBikes, Full Cycle, Outdoor Divas & more!
  • Much more!
  • And if you volunteer for 3 trail days during Dig to Win, you get a BMA trailbuilder t-shirt!

How it works:

Volunteer for at least 3 hours at any trail work party on the BMA Calendar to earn one entry to the drawing:

  • 3 hour evening trail project - 1 entry
  • 6 hour weekend trail project - 2 entries
  • Weekend trail project - 4 entries

The BMA Trail Fund

Boulder Mountainbike Alliance is raising funds and volunteer power to repair and re-build trails damaged by the flood waters. Money raised will be allocated to trail and restoration projects, propelling volunteerism, purchasing tools, training trail crew leaders and reinvigorating the riding experience in Boulder County. Throughout 2013 and 2014, BMA will be working with its agency, business and non-profit partners to organize trail work days and harness our community's volunteer energy and muscle.

In addition to addressing flood damage, the BMA Trail Fund will fuel efforts to build an improved and expanded trail system at Magnolia with the USFS and to realize regional trail connections throughout the county.

List of What We'll be Spending TRAIL FUND $$ on:


  • We're shooting for 15 trail project next yr (vs 10 this yr)
  • Maintaining the Marshall Mesa/Doudy Draw trail system
  • An additional trail crew leader training (2 per yr vs 1)
  • A volunteer coordinator to organize and oversee trail projects
  • Tools/Equipment
  • BMA merchandise for the most dedicated trail builders (e.g. crew leader shirts). Food/Beer/Props for the volunteers.
  • infrastructure like bridges, signs, cattle crates, etc
  • Professional trail planning/design services
  • incentives to promote volunteerism and trailbuilding


More About BMA's Trail Work

Check out BMA's Trail Project History to see all the places where BMA has improved or created the trail experience for everyone.

Boulder was one of the first communities where mountain biking emerged, but and we were the first to ban it over 20 years ago. With successes like the opening of Doudy Draw Trail to mountain bikers, the creation of Picture Rock Trail, and Valmont Bike Park, we've shown that mountain bikers are good stewards and valued partners.

The City of Boulder, the County of Boulder, and the Forest Service recognize BMA as a committed partner thanks to the trail building expertise we bring to the table, and the thousands of volunteer hours we donate. Last year alone, BMA donated over $500,000 worth of volunteer time.
