Course Details

Course Information

The race course is 5.7 miles (9 km) long, with 735 feet of climbing each lap. Trails are heavily wooded, approximately 60% old narrow double track, 40% single track, with the start/finish alongside a beautiful lake. Climbs are moderate, except for one steep climb, and are typically loose and rocky. 80-90% of the trails are well drained and rocky and remain fairly solid in wet conditions, although some mud may be encountered on the newest single track and stream crossings during wet weather. Dry weather brings fast, rocky trails.
