The Ed Sias Cross Country Invitational (ESI), hosted by Campolindo & College Park High Schools, has been successfully kicking off the prep Cross Country season in the East Bay for twenty-two years! Hidden Valley Park'Â’s winding trails & varying terrain create the most popular racing venue in the area. In addition to being the official ESI course, the park has been the site for the Tri-County Athletic League Championships, the Diablo-Foothill Athletic League Championships, the North Coast Section Championships, & the Golden Gate Conference Jr. College Championships.
