Inspired by the success of women’s races like the Nike Women’s Half Marathon in San Francisco each October, Indiana’s capital city got its own women-only race event in 2011 with the debut of the Indianapolis Women’s Half Marathon & 5K. Now set for its 12th annual running, the race takes runners on an out-and-back course that loops through the city’s downtown districts and follows a stretch along the banks of the White River, which flows through the city.
