Races Near Me: Upcoming Running Races

From the base of Table Mountain and Colorado's spectacular foothills, All-Out Multicourse presents our 15th annual Kooky-Spooky from Jefferson County's NAAC Stadium… easily accessible from several nearby highways. Along with its Endless Series sidekick in March, Spring Fever, these 5K, 10K & Half Marathon courses will hug the shores of Arvada's Blunn Reservoir via the Ralston Creek Trail and will challenge the beginner and veteran athlete alike! Of course, we'll still be celebrating the Halloween spirit so re-use your Halloween costume for our official costume contest. And especially revel in the extra hour of sleep you get as Nov. 1 is the end of daylight savings time!

Most races are designed for one person: You. Your PR. Your medal. Your ego. Running is, by its very nature, a deeply selfish endeavor. In November, we flip the script. Welcome to The Unselfish Ultra: an HPRS event built entirely around thinking of someone other than yourself. This is not about chasing an award or feeding your Strava profile. It’s a multi-hour reckoning across the Denver Metro, designed to remind us that we share this space and that our legs can lift others up.
