course description

The Canyons 50K is run mostly on single-track, from Foresthill to the Swinging Bridge and back, along the historic Western States Trail. The start/finish/village is at the old Foresthill Elementary School. You will head East on Foresthill Rd, left on Bath Rd and then pick up the single track at 1.5 miles as you drop into Volcano Canyon. You will climb sharply then roll along to Michigan Bluff at mile 6.2 followed by a nearly 3 mile 1800 feet drop down El Dorado Canyon at mile 9. The biggest climb of 2500 feet is next, up past Deadwood Cemetery to the water Pump at mile 13.5. Finally passing by Devil's Thumb and plunging down the extremely steep and twisting descent to the Swinging Bridge at the turn around. Truly some of the finest single-track anywhere with views to match. Click Caltopo for a link to the map.
