The Nationwide Better Health Columbus Marathon and ½ Marathon will both start on the corner of Broad and High streets, but the ½ Marathon course will deviate from the Columbus Marathon course in Bexley — leaving the Columbus Marathon course from Drexel onto Elm — and rejoining the course on Columbia in order to finish on Nationwide Blvd with 13.1 miles. ½ Marathon runners will start with the rest of the field at 7:30 a.m. The total Nationwide Better Health Columbus Marathon field (marathon and ½ marathon participants) will have a ceiling of 11,500 participants.
