Santa Rosa Marathon

Santa Rosa Marathon is held on August 21, 2027, in Sonoma County, California, on roads lined with vineyards. The marathon (26.2 mi) starts at 6:30 a.m., the 10K (6.2 mi) at 7:00 a.m., the half marathon (13.1 mi) at 7:30 a.m. and the 5K (3.1 mi) at 9:00 a.m.

Wine-country mornings in August are cool and often foggy until mid-morning, and the schedule here is built around that: the marathon leaves in the dark and finishes before the valley warms. Take the early start as the gift it is — the same course three hours later would be a completely different race.
