The OverGRound Marathon and Relay
The OverGRound is a free, unofficial marathon and marathon relay held in Grand Rapids on October 25, 2026. The event is co-hosted by local running and fitness communities and is described as inclusive and community focused. This is the third running of the OverGRound and is noted as the first known marathon held fully within Grand Rapids city limits.
The route is designed to showcase a range of city features and neighborhoods beyond Butterworth and Millennium. The course passes coffee shops, varied neighborhoods, cityscapes, and parks before returning to Veterans Memorial Park. The event is mostly self-supported, with wayfinding guidance, multiple aid stations on course, and bikers and volunteers who check in with runners. All paces are welcome, and every participant receives a welcome back at Veterans Park.
The relay option allows any team configuration or leg distances; teammates determine how to divide the 26.2 mile route, and coffee shops are suggested changepoints. Participants are encouraged to bring their own bibs. The event lists volunteer opportunities the day before and the day of the event. Registration for 2026 is free; a participant guide for 2026 is noted as forthcoming. Visit the organization's website for the most recent information.
