The Miwok 100K is very hilly (approximately 10,000 feet of cumulative elevation gain) with spectacular views of San Francisco and the Golden Gate Bridge, Mt. Tamalpais and the Point Reyes National Seashore. The course is a modified out-and-back, consisting of mostly fire roads and single-track trails with approximately five miles on roads. The race is extremely competitive at the front, a rewarding challenge for the mid-pack and a glorious long day in the forests and fields for those not in a hurry.
