There is parking available onsite at the Lake Sammamish Boat Launch, adjacent to the Start/Finish line. WA State parks require a Discover Pass. If you do not already have a Discover Pass, you may purchase a day pass for $10 at an onsite parking kiosk. Alternatively, you may pre-purchase a Discover Day Pass for $10 and we will include this pass in your registration packet, which will be available for early pick up on 10/25 if you wish. There is also overflow parking .75 mi away at the ISD Admin building parking lot.

Registrations submitted by 10/08/24 include a 2024 MM5K Race Tee & Medal
