15 challenging miles of singletrack riding around the Buffalo Headwaters on trails that have recently been given official designation by the Ozark National Forest as the Upper Buffalo Mountain Bike Trail System. A very technical ride will take expert and intermediate riders 2-3 hours to complete. These 15 miles make up the Half Challenge and finish at the start line. After a food/warmth break, riders can continue on to complete the entire 35+ mile Challenge ride finishing at the White family homestead along the Big Piney creek. Food and beverages are provided at the finish line & shuttles will be available. This is an invitational ride available only to OORC members. http://www.ozarkoffroadcyclists.com/html/ozark_headwaters_challenge.html
