Welcome

Eureka! Two Weeks of World Class Map Events in the World's Favorite Playground!

Whether uttered by Archimedes in Ancient Greece, miners during the California Gold Rush, or participants of the Cal-O-Fest (when discovering the awe inspiring orienteering terrain California offers), the term "Eureka!" is a fitting motto not just for the State of California (yes, it is the state's official motto), but for this Cal-O-Fest as well.

"Eureka" is Greek for "I found it" and it is a simple, beautiful way to express something that we, as orienteers, experience a lot in this sport we know and love. Every time we come upon that orange-and-white control marker, our inner voice erupts "Eureka!" and we are filled with an instant shot of joy, energy and excitement. We know you will be filled with the same joy and excitement over and over during this crazy cool navigation sports party in the woods.

California really is that amazing - come see for yourself.

In recognition of Native American Heritage Month, we send this message:

We run in the footsteps of those who came before us. CalOFest acknowledges the indigenous people in whose ancestral lands our events take place. Golden Gate Park and Presidio National Park are on the unceded homeland of the Ramaytush Ohlone peoples who are the original inhabitants of the San Francisco Peninsula. Morgan Territory Regional Preserve is located within the traditional homeland of the Volvon, one of five Native American nations in the Diablo area who spoke dialects of the Bay Miwuk language. You may see the evidence of their presence in the stones where they made mortars to grind acorns and constructed their village. For thousands of years the Wasiiw, now called Washoe, lived in the Lake Tahoe area from snowmelt through summer. The Washoe still live in their ancestral lands today. The valley's creeks and marshes provided game and forage for the Wasiiw, who knew this land intimately and worked with it wisely. We recognize and honor their history, traditions, and care.
