Ten Trails Active Club Trot n' Treat Relay Scramble

The Ten Trails Active Club Trot n' Treat Relay Scramble is an 11 km running event in Black Diamond, Washington, starting at 23089 SE Fir St. It is part of the Ten Trails Active Club series and uses a late-October, Halloween-themed format instead of a standard solo road race. The name indicates this is a relay scramble, meaning runners compete as part of a team rather than in an individual 11 km effort. The TrainerDay listing does not provide a detailed route but places the race within the Ten Trails area of Black Diamond, centered around the Trot n' Treat theme.
