All-Out Fall Fest

The All-Out Fall Fest is an annual running event held in Westminster, Colorado, featuring Half Marathon, 10K, and 5K distances, along with virtual options for each. The race courses wind southwest along the scenic Big Dry Creek Trail, offering stunning views of Standley Lake and the Flatirons. This event embraces a fun, nostalgic 70s theme and supports #themarshalleffect, a charity focused on youth suicide prevention.

It is also an official qualifier for the BOLDERBoulder 10K race. The Fall Fest is part of the Run Amok Fall Series, encouraging participants to register for multiple races with discounts. The event promotes a welcoming atmosphere to kick off the fall season. Visit the organization's website for the most recent information.
