The Nationwide Children’s Hospital Columbus Marathon is an annual road-racing event in Columbus, Ohio that features a full marathon, half marathon and community races on a predominantly flat, fast course that appeals to recreational and competitive runners. The event is notable for its long-standing partnership with Nationwide Children’s Hospital and for its ‘Mile Champions’—patient ambassadors who cheer runners along the course—making the race both a high-quality competition and a major local charity celebration. Routes take runners through downtown Columbus and nearby neighborhoods, drawing a large, community-focused field each year.
