The Pikes Peak Marathon, founded in 1956, is the oldest continually held marathon in the United States, taking runners from Manitou Springs, Colorado, to the summit of Pikes Peak at 14,115 feet, and back down for a total of 26.2 grueling mountain miles. It and its sister race, the Pikes Peak Ascent, each climb about 7,800 vertical feet up the historic Barr Trail on the east face of the mountain. The Ascent, which climbs 13.3 miles to finish at the summit, used to be held on the same day as the Marathon but became its own event in the 1980s due to its popularity.
