From the base of Table Mountain and Colorado's spectacular foothills, All-Out Multicourse presents our 12th annual Spring Fever from Jefferson County's NAAC Stadium… easily accessible from several nearby highways. Spring Fever has us looking forward to spring, spring flowers and our friends the bees! And this year, it lines up with St. Patty's Day so you know we'll be celebrating sláinte in Irish style. Along with its Endless Series sidekick in October, Kooky-Spooky, 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!
