From the base of Table Mountain and the stunning foothills of Colorado, All-Out Multicourse proudly presents our 13th Annual Spring Fever, benefiting our NEW charity partner, UpRoot Colorado! Conveniently accessible from several nearby highways, Spring Fever celebrates the arrival of spring, blooming flowers, and our buzzing friends the bees with our mascot Buzzby. Alongside its October endless series counterpart, Kooky-Spooky, this event features 5K, 10K, and Half Marathon courses that trace the scenic shores of Arvada's Blunn Reservoir via the Ralston Creek Trail. Both novice and experienced athletes will find these courses a rewarding challenge!
