About
A community marathon, relay and half marathon held each June in Kent, Washington, known as a social-distance-friendly event with no awards and a donation-based model supporting Northwest Harvest.
Catering & aid stations
Aid stations offer water, sports drink, and light food (e.g., granola bars, fruit). No on-course pasta or heavy meals; options are simple and geared toward quick replenishment.
Pacers
Pacers are provided for select start waves to help runners meet target times. On race day (Renntag), pacers run with flagged vests and announce split times; refer to the event schedule at the start corrals for wave-specific pacer assignments and target times.
