All-Out Fall Fest

The All-Out Fall Fest is an annual running event held in Westminster, Colorado, featuring Half Marathon, 10K, and 5K races, along with virtual options for each distance. The course follows the scenic Big Dry Creek Trail, offering views of Standley Lake and the Flatirons, creating a picturesque fall running experience. This event embraces a 70s nostalgia theme and supports #themarshalleffect, a charity focused on youth suicide prevention.

It is also an official qualifier for the BOLDERBoulder 10K race. Participants can join in person at Church Ranch Office Park or run virtually, making it accessible for all. The Fall Fest is part of the Run Amok Fall Series, encouraging runners to register for multiple events with discounts. Visit the organization's website for the most recent information.
