Welcome to the One-Eyed Dog! This cross-country endurance race is held over some of the most rugged and unforgiving sections of the Ozark Trail. Just when you think you can catch your breath going down, you’re facing back up a hill grinding out over rocks and roots. Boasting the only 100-mile, 100% singletrack race in the USA and over 11,000 feet of climbing, the OED100 mile is a grueling challenge that tests one’s physical and mental toughness. Finishing in daylight is a right of passage for any cross-country OED 100 mile endurance racer.
