Registration for the 2019 run is easy – sign up online at through May 31 and in-person on race weekend. King County Employees can create or join a King County Team and use the promo code KC5 to receive $5 off their registration. The event promotes fitness and community involvement and has raised more than $300,000 for King County Parks in the past nine years.
