Event description

The Birthday Run is a January running and walking event that includes a short course, a half marathon and a marathon. The event celebrates participants who have birthdays in January and includes cake at the venue. An aid station is available at the start and finish for clothing changes and snacks. Times are recorded at the finish and a wooden finisher item is given to finishers.

Course and location

Start location is at the north end of the Kirkland Corridor Trail at 120th Pl NE and NE 124th St. Parking is available near LA Fitness and the adjacent Shell gas station.

Distances:

  • Short Course: north 1.6 miles out and back; south 1.7 miles out and back
  • Half marathon: two repeats of the short course route
  • Marathon: four repeats of the short course route

The Kirkland Corridor may have construction on the far south end, so the short course configuration will be used. The course is not closed to traffic, is lightly marked, and participants should follow traffic signals and route directions. An early-start option is mentioned; participants who start before daylight should bring a headlamp or flashlight.

Registration and fee

Registration is through Webscorer. The listed fee is $35. Registration closes three days before the event; day-of registration is available for $45 cash. Visit the organization's website for the most recent information.
