The All-Out Fallfest 1-5k, 10k, and half-marathon, is a fall event through Big Dry Creek Trail. One of Colorado’s favorite trails meets one of its most glorious parks at this annual race! 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 marathon athletes. A course that’s not too hilly & not too flat makes this the perfect choice for athletes of all abilities & preferences. It's the only groomed trail marathon course in the Denver Metro Area!
