The International Mountain Bicycling Association (IMBA) is a non-profit organization dedicated to creating, enhancing, and preserving great mountain biking experiences. IMBA's mission is to create, enhance, and protect great places to ride mountain bikes, and to promote responsible mountain biking practices that benefit everyone.
As a chapter member of IMBA, the Ozark Off Road Cyclists (OORC) benefits from IMBA's expertise in trail design, construction, and maintenance, as well as advocacy efforts on behalf of mountain bikers. The OORC works closely with IMBA to ensure that the trails they build and maintain are sustainable, environmentally responsible, and enjoyable for riders of all skill levels.
Since its founding in 1997, the OORC has been dedicated to building and maintaining soft surface trails in the Arkansas Ozarks and Arkansas River Valley. The organization's efforts have helped to create a thriving outdoor community in the region, with opportunities for hikers, mountain bikers, and trail runners to enjoy the natural beauty of the area. The OORC regularly partners with local, state, and federal land managers to ensure that their trail-building efforts are in compliance with environmental regulations and conservation principles.
In addition to building and maintaining trails, the OORC is also committed to advocating for appropriate multi-use trail systems that benefit all trail users. The organization believes that trails should be accessible to a wide range of users, and that a collaborative approach is necessary to ensure that everyone's needs are met. As a chapter member of IMBA, the OORC is part of a larger network of organizations and individuals who share this commitment to sustainable, responsible, and enjoyable mountain biking experiences.

For anyone who may have missed the news the challenge has been postponed and will now take place 2/20-2/22. Don’t show up tomorrow! As of yesterday afternoon very little has melted and a plow had shown up for the first time on Cave Mtn Rd. Many thanks to attendees for their understanding, support and the committee of volunteers that puts this event together. They basically have had to do it all over again in a very short amount of time. Three weeks and we will try again!
Thanks to all of our sponsors for working with us on the new dates for the challenge. Great news we were also able to keep @chucky_waggs and @justinlarkinmusic on the new dates as well. Now we need you to support your OORC and get registered!
OORC has made the decision to postpone the Buffalo Headwaters Challenge to Friday, February 20-Sunday, February 22.
We don’t take this decision lightly, but our paramount concern is making sure riders and runners can experience the Headwaters safely, which is not possible due to snowfall and expected temperatures this week. We’ve had OORC members out at the Headwaters monitoring the impacts and they’ve reported ice on trails which will take a significant period to melt, and the likelihood of single digit or lower temperatures for camping overnight.
If you can’t make it in February, please reach out to us by FEBRUARY 12 about transferring your registration to 2027. There are no refunds given this is our annual fundraiser and all proceeds go back into these trails.
Please reach out to oorc.club@gmail.com with any questions - otherwise we’ll see you in February for the best party in the woods you can imagine!
This has been a long process but these flags are a great indicator of things to come. We hope you all have a great weekend. We kicked ours off out in the woods before this storm hits. Speaking of said storm we will update everyone on the 21st Annual Buffalo Headwaters Challenge on Sunday after we see where we are at winter precipitation wise. We will let you know now that if the decision is made to postpone we will be moving to the weekend of 2/20. Stay warm friends and we will update ya soon!
Online registration closes in 10 days for the 21st Annual Buffalo Headwaters Challenge presented by @adventuresubaru. Come help us celebrate over 10k volunteer hours in 2025 as we recognize our volunteers of the year, say thanks to some outgoing board members and welcome in some new ones.

Tomorrow we will share routes, schedule and important information about this years challenge! Get registered and support your OORC. Thank you to all the volunteers who came out this weekend. You’re the best! 🤘🏽🤘🏽

We did stuff this weekend. You can now roll Traverse all the way down to the back lot at Kessler. Thanks crew. Tuesday we have group rides from the smokehouse at 6pm. Saturday we are out at headwaters for course marking and some tread repair . We will also be adding to our certified sawyers numbers with a group of 5 headed to training and testing on Saturday. Have a great week and hit that registration for headwaters. One of a handful of grassroots local events left. Thanks!
More Wedington luv this morning. We finally put a fix in for the giant rootball that pulled the tread out on Don. Cleared the newly reported tree on Don and cleaned up a nice connector across from the paved lot to connect to Lakeside Trail without riding down the highway. Join us tomorrow at Kessler. We will meet in the back lot at 8am. Come give back to the trails you love!
