Nationwide Children's Hospital Columbus Marathon & Expo 2026

Approximately 15,000 participants were expected downtown.

The expo and packet pickup were in Hall D of The Greater Columbus Convention Center, 400 N. High Street, Columbus, OH.

The organizer listed marathon, half marathon, 5K and 1-mile runners and their families.

The expo was a required stop for entrants in the marathon, half marathon, 5K or 1 mile, since nothing was mailed and each participant had to collect a bib, shirt and gear bag in person (or send a proxy) from Hall D. Anyone who was neither racing nor supporting a runner would have gotten little from it, because it was a pickup point with an ASICS exhibitor presence, not a program of talks or business meetings.

Runners and families at a race expo usually wear casual athletic clothing such as running shoes, tech tees and layers, and comfortable shoes helped during the expo hours on the convention center floor.

The organizer listed Nationwide Children's Hospital as Title sponsor and ASICS as an exhibitor. Its audience listing named marathon, half marathon, 5K and 1-mile runners and their families.
