One of Colorado's favorite trails meets one of its most glorious parks at our 8th annual Fallfest 5K, 10K, half & full marathon! 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, then the rustic nature to the northeast will be waiting to greet our marathon athletes.
A course that's not too hilly & not too flat makes this the perfect choice for all abilities & preferences. All-Out Multicourse is proud to bring you the one and only groomed trail marathon course in the Denver Metro Area!
