Santa Rosa Marathon
Santa Rosa Marathon is a rolling marathon in Santa Rosa, USA, held each August. Starts downtown and follows the Santa Rosa Creek Trail and Prince Memorial Greenway, then heads west on country roads through Sonoma County vineyards before returning to a downtown finish. Late August in Sonoma County is warm and dry, with temperatures of about 11 to 29°C, so the early start matters. With Santa Rosa Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
