OC Marathon is a flat marathon in Newport Beach, USA, held each May. A net-downhill point-to-point route from Fashion Island in Newport Beach through Corona del Mar and Santa Ana to the OC Fair & Event Center in Costa Mesa. The organiser mentions flat stretches. Early May on the Orange County coast is mild, with temperatures of about 13 to 22°C and low cloud common at the 5:30 start.
