Colorado > Autumn Color Run Half Marathon, 10K, 5K & Fun Run
Buena Vista, CO  •  Saturday, September 20, 2014  •  Course Map

This series of running events -- which include the race's signature half marathon as well as a 10K, 5K and a one-mile "fun run" -- are held in the upper Arkansas River valley town of Buena Vista, near Colorado's Collegiate Peaks mountains, and make their 30th annual running in 2014.

Buses pick up participants in the town's central park for transport to the starting line in nearby Cottonwood Lake to the west of town, for a half marathon that takes place on mostly dirt roads as the course makes its way into the town. The half course also includes about four miles of paved surfaces and significant changes in elevation -- from the starting point of the race, the half marathon course drops about 2,500 feet by the time runners arrive in Buena Vista.

Just over 430 runners came out for all four races combined at the September 2012 running of the race, which often helps runners set personal best race times thanks to its mostly downhill course. Of the total number of finishers, the half marathon saw the largest number with 235 runners crossing the finish line in the 13.1-mile race alone.

The race also takes place in a spectacularly scenic part of central Colorado known as the "Fourteeners Region," so called because it includes a number of mountains that exceed 14,000 feet in elevation, including Mount Elbert, Mount Harvard and Castle Peak.

The towns along the valley, like Buena Vista, Leadville and Salida, also offer plenty of things to do after the race, from camping, hiking and river rafting down the Arkansas River to seasonal art and music festivals.
