Grit City Backyard Ultra

Grit City Backyard Ultra is a backyard ultra format event held in downtown Tacoma, Washington. The course is a 3.33-mile loop through downtown Tacoma that passes the Bridge of Glass, the Glass Museum, and the Tacoma Dome and includes city views.

The loop is repeated every hour on the hour for up to 15 hours. Participants must return to the corral before the next hourly start to continue; those who stop between laps are recorded as an honorable DNF. Completing all 15 laps is recorded as a finisher.

The event structure creates breaks between laps that allow rest, refueling, and equipment changes. The description notes informal race-day routines such as the course emptying out lap by lap, eating between loops, and crew support at the corral. Crews may assist runners with food and fresh socks and provide encouragement during the event. Visit the organization's website for the most recent information.
