From the Organizer
The overGRound is a free, unsanctioned marathon and marathon relay through the city of Grand Rapids whose route showcases the variety of GR’s features and neighborhoods (beyond Butterworth and Millennium). This is an inclusive, supportive, and free running event celebrating community and a grassroots, no frills spirit of running and free fitness. It is a co-hosted event featuring the many wonderful running and fitness communities of Grand Rapids. Together, participating clubs can invite people out to run, cheer, and support runners on the course. The public is warmly welcomed to participate.
This will be the third running of the overGRound, the first (known) marathon held fully within GR city limits. Once again, it will be hosted by local participating clubs—to be announced soon!
This year the overGRound will be held October 25, 2026 at 8am, starting and ending at Veterans Memorial Park. The [subject to updates!] carefully designed course passes many coffee shops, a variety of neighborhoods, cityscapes, and parks before returning to Veterans Memorial Park.
Whether you run the marathon, organize a team to run the relay, or just show up to support the runners, let’s make it once again a fun, unique, out-in-the-open Grand Rapids event that goes beyond the norm.
More details:
- All paces welcome to participate, with every participant from last to first getting a welcome back at Veterans Park
- This is mostly a self-supported event, but there will be wayfinding guidance, aid stations on course, and bikers and volunteers who will check in with runners
- The marathon relay is open to any team configuration or leg distances; the coffee shops make good changepoints but "y’all do y’all" to complete the 26.2
- We encourage you to bring your own bibs and have fun with them
- The 2026 edition of the Participant Guide is not yet available—we will email you when it’s ready!
- The Facebook event is HERE and the Strava event is HERE for reference
- You are welcome to do any combination of the following: a) run the marathon, b) run as part of a relay marathon, or c) volunteer to help this event be a success, d) come out and cheer (just show up on the course, or at Veterans Park, on race morning).

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
Running
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
