We have partnered with Rainier Foot and Ankle to create this fun, family, fitness & WELLNESS event!

We will be starting and stopping at Rainier Foot and Ankle's beautiful location! The course runs along Railroad Avenue to the trailhead, then to the Dog park, and back! This is a fairly flat, easy course. It will require a police closure of Griffin Ave, so you may lose a few seconds of time waiting for traffic control.
