The Sloth Runners Race in Seattle is a small group run held in Lincoln Park, offering 5K, 10K, half-marathon, and Family 1 Mile distances. It is designed for runners and walkers, welcoming all paces and ages, provided those under 18 are accompanied by a guardian. Waves have capacity limits and are filled on a first-come, first-served basis. The in-person event may sell out, with a virtual option and a waitlist available when spots are filled.
The course map is sent via email before race day, and bibs are distributed at the park. Shirts and other items are mailed to U.S. participants, bypassing a traditional packet pickup. Timing is not mandatory, as no chips are used; runners may use apps like Strava or request assistance from coordinators for time recording. The sloth theme is represented by the post-run Sloth Charm. The swag bag typically contains a shirt, medal, finisher towel or giveaway, a digital training pack, online results, and a completion certificate. An eco-registration option is available without a shirt, alongside optional charity fundraising and a donation based on miles logged post-race.
