Gear Check

We will have gear transfer available at the start. In an effort to reduce waste, we will not be providing drop bags, so PLEASE BRING YOUR OWN BAG. We will have identification tags for you to use. Drop bags will be available to pick up at the race finish at Lake Sammamish State Park.  back to top


There is plenty of parking at Redmond Town Center. Please arrive early enough to find a spot, pick up your race packet, and get ready to start.

Finish Line Parking

Your friends and family are welcome to park at Lake Sammamish State Park to watch you cross the finish line. However, because it’s a state park, every vehicle is required to display a Discover Pass (good at all state parks and other state lands). You can purchase a pass in advance online or at the park’s automated pay station. Both one-day and annual passes are available.

Packet Pickup

Pre-race packet pickup


Join the party and pick up your packet at Road Runner Sports Bellevue.

Friday, March 1 10:30am-7:00pm

Road Runner Sports is located at 12200 Northup Way, Bellevue, WA 98005.

Required Documents

You will need photo ID in order to pick up your packet (both at pre-race pickup and on race day).

You can have someone else pick up your packet for you if they have:

  • a copy of your photo id: either hard copy or on phone
  • written authorization from you


In an effort to help our local communities reduce waste, we’ve decided to forego plastic bags and instead provide “virtual” swag. You’ll still be getting great discounts on other local races, as well as discounts from our great sponsors. But instead of handing out printed flyers in plastic bags, we’ll be sending a special email to all registrants with links to discounts on race gear and race entries. The best part: no plastic bags to throw away!


Parking at Road Runner is very limited. Please carpool or use public transportation if possible. There is also some additional parking just east of Road Runner (see map). Please do NOT park in any other lots.

Registration Confirmation

If you’d like to verify that you’re registered, please check the confirmation list.

Race Day Pickup

You may also pick up your packet on race day. If you choose this option, please allow plenty of time for transportation and parking. We strongly encourage you to pick up your packet ahead of time if you can.  back to top
