All-Out Runapalooza

The All-Out Runapalooza is an annual running event held in Arvada, Colorado, featuring half marathon, 10K, and 5K races, along with virtual options for each distance. Scheduled for August 2, 2025, the race starts near the award-winning Apex Center and follows the scenic Ralston Creek Trail. Participants enjoy relatively gentle courses that wind through shaded, creekside areas, open spaces, and charming golf course communities.

The event serves as a festive end-of-summer celebration and is part of the Run Amok Summer Series. It is also an official BOLDERBoulder qualifier, offering runners a chance to qualify for the 2026 BOLDERBoulder race. Visit the organization's website for the most recent information.
