All-Out Runapalooza
The All-Out Runapalooza is an annual running event held in Arvada, Colorado, featuring half marathon, 10K, and 5K race distances, along with virtual options for each. Scheduled for August 2, 2025, the races start from the award-winning Apex Center and follow the scenic Ralston Creek Trail.
