2026 Columbus Marathon - Oct 18

City loop marathon course in Columbus with 159m elevation gain. A flat, fast city loop built for PRs and Boston qualifiers — only about +523 ft (159 m) of total climbing, most of it a gentle rise through the middle miles. The single-loop route starts and finishes downtown near the Ohio Statehouse, then tours the city's most-loved neighborhoods: historic German Village, Bexley, Upper Arlington, Grandview Heights, and a pass through The Ohio State University. The course is USATF / IAAF / AIMS cert
