One of Colorado's favorite trails meets one of its most glorious parks at our 9th annual Fallfest 5K, 10K and half marathon! As the courses wind southwest along Big Dry Creek Trail, the remarkable sight of Standley Lake with the Flatirons on the horizon will come into view. A course that's not too hilly & not too flat makes this the perfect event for all abilities & preferences, plus… along with its Endless Series sidekick in April, Beat the Heat.
