Please Note:  Club trips are designed for licensed vehicles and often enter and exit at different locations. Trailered unlicensed off road vehicles could therefore violate motor vehicle laws when returning to the start. Be sure to consider this if you intend to drive an unlicensed off road vehicle. Official Club Radios are GRMS channel 19 for travel to-from an event and 5 for during an event. NOTE, subject to change by event leader.
HomeVolunteer Information
The Trailridge Runners 4WD Club has completed many OHV Recreation Grants through the Colorado State Parks over the years. Our largest was the Lefthand Canyon OHV Area Restoration Grant. We do annual volunteer projects with the Boulder Ranger District of the US Forest Service. We have maintained campgrounds, picnic grounds, done signing projects, and done road maintenance.

Annually we do volunteer projects on our 4WD Adopt-A-Roads to maintain motorized public access to public lands.
