Course DNA
The Course
Jerome dumps you on gravel and pavement into Clarkdale. Then red sandstone. Aids include Boynton Canyon, Devil's Bridge, Schnebly Hill, Munds Park, Casner Canyon, Oak Creek. Casner is a powerline corridor: loose sandstone and shattered volcanic rock, no water, full sun. Red Rock Crossing is the river. Pine loam takes over on the Coconino Plateau. Mount Elden trails close it. Low near 3,281 feet. High near 9,281. Trail 62 percent, jeep 29, paved 9.
The Work
Canyons run near 90°F. Plateau nights can hit 35°F. Heart rate works the climbs. Quads brake on off-camber sandstone steps all day. Train the heat-to-cold swing. Load the quads on technical downhills. The plateau climb will not wait for a shut stomach.
Kit
Sticky rubber on slick red sandstone. Cushion under it. Wide-brim hat with a neck cape and ice pockets. Ice the hat and the arm sleeves early. Core temp is the race on Casner.
Race Day
Bank nothing on the Jerome to Clarkdale drop. Gravel and pavement will shred the quads before singletrack. Nose-breathe Casner. It is waterless and fully exposed. Sedona crew access is congested. Park early at designated trailheads. Red Rock Crossing can rise. Towels and a full shoe change ready. Mount Elden trails confuse at night. Call the handoff.
