Bainbridge Island's beloved spring running event is back!

Join Bainbridge Island Parks & Trails Foundation in running or walking a 10k, 5k, or kids-only Fun Run on a scenic wooded course from Battle Point Park, along the Forest to Sky Trail, and looping among the towering firs of the Grand Forest.

Run for the Trails

Trillium Trail Run will launch the Foundation’s “Trails Connect Bainbridge Island” campaign, to build four new signature trails around the island: the Lost Valley Trail, nexus of the east-west, cross-island trail route from Winslow to Gazzam Lake; Dolphin Drive to W. Port Madison Trail; Sunny Hill to Nutes Pond Trail; and the Waypoint Woods gateway trail. All race proceeds benefit trail development.
