|Getting There:||The best place to start this loop is at the remote Long Lake or Mitchell Lake trailhead inside of Brainard Lake Recreation Area. The other main starting point is Buchanan Pass Trailhead, located about 4 miles west of Peak to Peak Highway.|
This is a rigorous but amazing, 26.4-mile high-alpine loop that sends runners through spectacular terrain on both sides of the Continental Divide in the Indian Peaks Wilderness Area. The loop, which circumnavigates Mt. Audubon (13,229 feet), Paiute Peak (13,088 feet), Mt. Toll (12,979 feet) and other big mountains on the western edge of Boulder County, is comprised mostly of mild to technical singletrack trails and includes 6,675 feet of vertical gain.
