The Santa Rosa Marathon weekend offers over 6,000 runners from across the U.S. and abroad the opportunity to race through the scenic vineyards of the Sonoma County countryside, the City of Santa Rosa, and the Prince Memorial Greenway. Marathon racers also run through the DeLoach Vineyards barrel room ─ a once in a lifetime opportunity. The flat and FAST course is also U.S. Track and Field-sanctioned and certified, and the Marathon is a qualifier for the Boston Marathon.
