All-Out Beat the Heat 1M, 5K, 10K, Half Marathon & Marathon

One of Colorado’s favorite trails meets one of its most glorious parks at our 2017 Beat the Heat 5K, 10K, Half & Full Marathon! As all distances 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 event for all abilities & preferences, plus… along with its sister event in September (Fallfest), All-Out Multicourse is proud to bring you the one and only groomed trail marathon course in the Denver Metro Area!
