A stunning coastal route in Wilder Ranch State Park.

A benefit for Bike Santa Cruz County: promoting active transportation by making Santa Cruz County a better place for bikes, through advocacy, education, and community engagement.

Run by the Sea is a gorgeous half marathon, 12K run, or 4K run/walk that meanders along the undeveloped coastline north of Santa Cruz. Most of the run is on a flat, packed dirt trail, and overlooks wild rocky shoreline. No other running event uses the trail, and with a legendary beach crossing, Run by the Sea is unique in every mile.
