The bottom line

A quietly fast race that does not ask for much beyond honest pacing.

Columbus Marathon is a strong choice for a PR attempt, and Columbus offers very little meaningful elevation. The tradeoff is that nothing about it is extreme in either direction.

Why runners choose this race

A loop course around Columbus, OH, with gentle rollers but no sustained climbing.
