Course records
The cruxMt. Baden-Powell and the hot drop into Chantry Flats
Course DNA
Sandy exposed singletrack. Steep granite chutes across the San Gabriels. Mt. Baden-Powell is the early mountain tax. Then the hot drop into Chantry Flats on the second day. Dry. Dusty. Full Southern California sun. Chilao is a crew hinge on the new 2026 line. Low near 1,152 feet. High near 6,188. Trail 80 percent, jeep 15, paved 5.
Dry heat at altitude. Heart rate climbs. Fluid leaves fast. Quads take the long descents. Train heat. Vertical descent blocks. Salt and water have to be precise before Chantry cooks what is left.
Breathable shoes with a wide toe box. Feet swell in the heat. Gaiters for fine granite sand. Dust bandana or buff to filter the dry mountain trails.
Calm breathing on the long climbs. Dry dusty air will tear a throat if you gasp. Hike the steep grades. Hydrate. Salt. Baden-Powell, then Chantry Flats in the heat. Chantry Flats and Chilao are the crew points. Cold sponges. Ice. Fresh bottles. Dry socks and shoes. Liquid fuel when food dies. Keep the stop on cooling.
