Run by the Sea is a set of road and trail races held at Wilder Ranch State Park in Santa Cruz on October 4, 2026. The event includes a Half Marathon, a 12K race, and a 4K run/walk. Now in its tenth year, the event is organized by the Santa Cruz Track Club and benefits the club’s youth program, Bike Santa Cruz County, and Santa Cruz Mountain Trail Stewards.

The courses mostly follow packed dirt trails and coastal bluff paths along the Monterey Bay. Much of the terrain is flat and passes through the park meadows and bluff-top viewpoints, offering open coastal views. Participants may also see marine life from the route.
