About
Sloth Run 5K/10K/13.1 SEATTLE, held in Seattle on August 28, 2027, offers four distances at 7:30 a.m.: a half marathon (13.1 miles / 21.1 km), a 10K (6.2 miles), a 5K (3.1 miles) and a Family 1 Mile Fun Run. The idea is a low-key race experience for runners and walkers of every age and level, moving at a comfortable pace in a supportive setting without the stress of competitive timing.
Participants can choose a virtual race instead, and the start is split into several waves. Everyone gets a race T-shirt, a finisher medal and access to local running clubs. The event sets out to bring the community together, encourage physical activity and support charitable causes through the miles covered.
