21 Races to Run and Walk in Northern Colorado this Fall

Northern Colorado is famously a runner-friendly community. In fact, Fort Collins is a Road Runners Club of America Official Runner Friendly Community! That might be because of our intricate system of parks and trails or perhaps it’s our proximity to some of Colorado’s most impressive scenic routes. We think it’s a combination of those plus NoCo’s lineup of marathons, half marathons, 5Ks, training races and other fun running events!

Autumn in Northern Colorado offers impressive changing colors and some of the best running conditions before the snow falls! Check out the region’s best, most anticipated races so you stretch your legs with our community of running fanatics.
