The work

What they do

Trail building, advocacy, and education for mountain biking access on public lands. Works with USFS and BLM on trail designations and management.

Every year they sign one sentence and file it with the federal government: “Education of mountain cyclists.”

General advocacy & education - The organization works to create innovative trail management solutions and enhance cooperation among different trail user groups. The organization also educates cyclists and promotes responsible off-road cycling through the distribution of written and electronic materials, including the publication of a monthly email newsletter and regular social media content. In addition, the organization encourages low-impact riding and volunteer trail work participation.-Continued on Schedule O-

That ratio is a good sign, not a scorecard. Plenty of great groups run leaner and lumpier. What matters is the extremes, and IMBA is nowhere near one.

Backed on the record by Walton Family Foundation, latest filing FY22.

$1,140,292 programs, $80,042 management, $0 fundraising. Form 990, FY2016.

Chairs the 14-member board.

Honesty note: leadership comes from each year’s federal filing, so it can run a year behind. This one caught a changing of the guard in the act: the FY2016 officer table lists Dan Brillon, the return itself is signed by Dave Wiens. Orgs that claim their page can update it same-day.

Those 14 volunteers are people who decided this ground was theirs to defend. If IMBA is fighting for your place too, the matchmaker will find your way in.
