All-Out Fall Fest

Yo, check out the mic! Lace-up for the 12th Annual Fall Fest, where the beauty of Colorado’s great outdoors meets the totally tubular fun of 80s nostalgia! The course takes you along the beloved Big Dry Creek Trail, winding southwest with stunning views of Standley Lake set against the majestic Flatirons. This event, which kicks off the fall season, is also the Endless Series sidekick to Beat the Heat. Come experience the breathtaking scenery in Westminster, CO, and embrace the dope spirit of the 1980s! This race is going to be bad!

This family- and dog-friendly event includes:

The flexibility of running or walking 5K, 10K, or half marathon distances to meet your fitness goals and so you can participate with your friends and family
An awesome water bottle, full-color medal, and event-specific bib for all distances
Chip timing and accurately measured courses
Tubular post-race meal including breakfast burrito and chocolate milk
Lots of free course and finish line photos

We are inclusive and support athletes of all abilities, including no time limit on the run/walk
