All-Out Spring Fever
About the event
All-Out Multicourse is proud to host our 15th Annual Spring Fever, a rewarding event for both novice and experienced athletes set against the backdrop of Table Mountain and the stunning Colorado foothills. This spring celebration, featuring our mascot Buzzby, includes 5K, 10K, and half marathon courses that trace the scenic shores of Arvada's Blunn Reservoir via the Ralston Creek Trail. Conveniently accessible from nearby highways, Spring Fever is the endless series spring counterpart to Kooky-Spooky, and proudly benefits our NEW charity, People and Pollinators Action Network (we really love the bees). And don't miss that you can use Spring Fever to qualify for your BOLDERBoulder wave!
