Want to get involved? There are many ways you can help GROC's mission to provide quality multi-use trails to the greater Rochester area. GROC is a registered non-for-profit organization made possible by volunteer effort, and every little bit of help we can get goes a long way! Not into digging? Check out our chapter of the IMBA Mountain Bike Patrol.

Trail Crew

Like to get your hands dirty? Want to help decide where and how new trails get built? Volunteer for the GROC Trail Crew. Join the Trail Crew Meetup to get notifications of upcoming trail work days, meetings, and special projects. During peak season, we may have trail work days every week, so be sure to sign up!

Never dug before? Don't worry! There's a first time for everything, and our trail work coordinators will provide instruction on the right way to dig a trail (yes - there IS a right way!). Bring work gloves, water, bug spray, and durable footwear!

After you do trail work, don't forget to log your volunteer hours so you can get credit where credit is due!

Mountain Bike Patrol

GROC PATROL is our local IMBA National Mountain Bike Patrol group. GROC Patrol has 20+ members who are out on our local trails and volunteering regularly. We are starting to expand our available legal trails and we encourage those who want to help create a great experience for all riders to join GROC Patrol.

IMBA’s National Mountain Bike Patrol (NMBP) consists of dedicated volunteers partnering with land mangers, landowners and emergency personnel to assist, educate and inform all trail users in order to enhance their recreational experience. The NMBP program organizes and supports more than 50 volunteer bike patrol groups and 600+ trained patroller throughout the United States and the world.

Patrollers promote responsible mountain biking through IMBA's philosophy of environmentally sound and socially responsible riding, embodied in the universally recognized IMBA Rules of the Trail.
