Spring Run for Fun @ Bridle Trails

This trail running event takes place at Bridle Trails State Park in Kirkland, Washington. The park is described as a nearly square-mile forested area with dozens of miles of trails, situated close to Seattle and Eastside communities. It is typically snow-free and accessible year-round due to its low elevation.

The event offers four distance options:

  • 5 km
  • 10 km
  • Half Marathon
  • Marathon

The courses utilize a 6.55-mile loop within the park. Runners can expect mostly wide, smooth trails with a gently rolling elevation profile, featuring an initial uphill section followed by flatter terrain and a final downhill stretch.

Aid stations offering water, electrolyte drink, and snacks are located on the course and at the start/finish area. Parking is available inside the state park, but a Discover Pass is required. A youth runner discount is offered for elementary, middle, or high school participants. Visit the organization's website for the most recent information.
