Organiser's Description

From the base of Table Mountain and Colorado's spectacular foothills, All-Out Multicourse presents our 14th annual Kooky-Spooky from Jefferson County's NAAC Stadium easily accessible from several nearby highways. Along with its Endless Series [https://www.alloutmultipro.com/endless-series] sidekick in March, Spring Fever [https://www.alloutmultipro.com/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 (or take advantage of those post-Halloween sales) for our official costume contest. And especially revel in the extra hour of sleep you get as Nov. 2 is the end of daylight savings time!
