From the Race Organizer
Trick-or-Treat can wait! 🎃 Join us for an urban Score-O orienteering adventure across one of California’s most dynamic campuses—where sun-soaked coastal bluffs meet cutting-edge research facilities, and hidden courtyards give way to modern architectural icons. Established in 1960, UC San Diego spans over 2,178 acres in beautiful La Jolla—right by the Pacific. It’s home to distinctive landmarks such as Geisel Library, lush eucalyptus groves, and the winding “Snake Path” at the heart of campus. Whether you’re a first-timer or a seasoned navigator, this event invites you to explore the campus like never before—map in hand, compass set, and ready for discovery. Bring your friends and find your way through this vibrant campus maze of research hubs, plazas, and hidden gems.
