Spring Run For Fun @ Bridle Trails

The Spring Run For Fun takes place at Bridle Trails State Park in Kirkland, Washington. This nearly square-mile park features an upland forest with wetlands and dozens of miles of maintained trails. Sitting at an elevation of 500 feet, the area is typically snow-free and accessible throughout the year. The courses consist of wide trails with a gently-rolling elevation profile and few steep slopes, though some sections include narrower paths with rocks and roots.

The event offers several distances:

  • 5 km (one loop on the west and east sides)
  • 10 km (a 6.55-mile loop touring the eastern trails)
  • Half Marathon (two laps of the 6.55-mile loop)
  • Marathon (four laps of the 6.55-mile loop)

The 5 km course climbs for the first mile before flattening out and descending for the final section. The 10 km, Half Marathon, and Marathon routes follow a 6.55-mile loop that features an uphill start followed by a rolling profile and a downhill finish.

Participants have access to aid stations stocked with water, electrolyte drinks, and various snacks such as energy bars, gels, fruit, and salty foods. The Marathon includes seven aid station visits, the Half Marathon includes three, and the 10 km includes one. A Discover Pass is required for parking within the state park. Because the park is shared with equestrian users, participants must yield to horseback riders by stepping to the side of the trail and speaking to the rider.
