Event Description

One of Colorado’s favorite trails meets one of its most glorious parks at our 5th annual Fallfest 1M, 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, plus… along with its Endless Series sidekick in April… Beat the Heat, All-Out Multicourse is proud to bring you the one and only groomed trail marathon course in the Denver Metro Area!
