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.
