The beautiful Swinging Bridge over the American River is a lovely spot and an iconic location on the Western States 100 course. Located just before the 2 mile, 1800 foot climb up to Devil's Thumb, this river crossing marks the 46-ish mile of the race and the bottom of the very steep Deadwood Canyon descent. After reaching the top of Devil's Thumb, the El Dorado canyon is a 2,600 foot descent back to the river before you climb back up another 1,800 feet to reach Michigan Bluff. A great place to practice those climbs and descents!
