All-Out Runapalooza

Website Registration

The All-Out Runapalooza is an annual running event held in Arvada, Colorado, featuring half marathon, 10K, and 5K races along the scenic Ralston Creek Trail. The courses offer relatively gentle terrain through shaded, creekside areas, open spaces, and charming golf course communities, making it accessible and enjoyable for runners of all levels. The event also offers virtual race options for all distances, allowing participants to run anywhere, anytime.

As an official BOLDERBoulder qualifier, runners can use their finishing times to qualify for the 2026 BOLDERBoulder race. The event supports Colorado veterans through donations benefiting Salute Colorado. Visit the organization's website for the most recent information.

Always double-check with the organizer's website – things can change, and we might have sprinted past a few details!
