Albuquerque, NM. Combines the traditional 6- or 12-hour endurance bike races we love with a 5K, 10K, 20K, or 40K trail run. The trail is an exciting, slightly technical, 90% singletrack loop that flows through the pine and oak trees of Cibola National Forest. This course is 12.1 mi. long with a 1,200 ft. elevation gain.
