The Course

One of the most beautiful courses in the nation will take you on a journey through classic California - a turn-of-the-century (19th century that is) downtown, historic neighborhoods with Victorian and Bungalow houses, past a Frank Lloyd Wright building and Chinese Garden, out into the Edna Valley with Morros, vineyards and farmland and a downhill finish at the iconic Madonna Inn.

"In 27 years of racing over 400+ events around the world, your race made me feel like the way it was 'back in the day,' grassroots, local and the most friendly and encouraging team members. The Madonna Inn, spending time in wine country, seeing the sun and your great course running through farm country vs. big cities will have us coming back for sure in 2015!" -- Wayne Kurtz, racetwitch.com
