One of Colorado's favorite trails meets one of its most glorious parks at our 9th annual Fallfest! As courses wind southwest along Big Dry Creek Trail, the remarkable sight of Standley Lake with the Flatirons on the horizon will come into view. Its Endless Series sidekick in September is Beat the Heat.
