Welcome to Relay Around Columbus. The inspiration for Relay Around Columbus comes from the various relay events around the country and the natural course located in around Columbus. What makes RAC unique is that it is a ‘Metro Relay,’ as it is entirely in a metropolitan area as compared to being located, for the majority of the event, in the country. Ninety percent of the RAC course is on paved trails, or in parks, in and around Columbus. The event will be for 6 persons and have length of 105 miles for running, and 70 miles for walking. The map below is a greenways trail map of central Ohio where RAC is held.
