About the Mission Inn Run Half Marathon
Few Southern California road races have run as long as the Mission Inn Run, which has anchored downtown Riverside since the late 1970s. The half marathon leads a morning of 5K, 10K, and kids events, with proceeds supporting the nonprofit Mission Inn Foundation and Museum.
Course
The half starts in downtown Riverside before the sun is fully up and winds through the city's parks, landmarks, and historic neighborhoods. The early start matters here, since inland mornings turn warm quickly.
Race-day weather
Mid-October in Riverside often begins in the 50s and climbs toward the 80s by late morning. The air is dry and the sun is strong, so the predawn start is a feature, not a quirk.
