Organizer's Description

Run by the Sea returns to lovely Wilder Ranch State Park on Sunday, October 5th! This unique Half Marathon, 12K run, and 4K run/walk meanders along the gorgeous coastal bluffs of California's Central Coast in Santa Cruz and consists mostly of flat, packed dirt trails. Participants will enjoy scenic coastal views while passing along the bluffs and Wilder Ranch park trails. Get ready to take in the natural beauty of the Monterey Bay, the serene flats of Wilder Ranch's meadows, and maybe even catch a glimpse of some dolphins - no other race is quite like it!

Now in its 10th year, Run by the Sea is organized by the Santa Cruz Track Club and benefits the track club's youth program, Bike Santa Cruz County, and Santa Cruz Mountain Trail Stewards.
