The TBK Bank Quad Cities Marathon is an annual running event based in Moline, Illinois, held on a late-September weekend since 1998. A USATF-certified, Boston-qualifying course, it sends runners over three Mississippi River bridges through four cities in two states, alongside a marathon relay, half marathon, 10K, 5K, and children's races.
Its multi-city route gives it strong regional sports identity.
The marathon is built entirely around its Mississippi River setting, promoted with the tagline five races, four cities, three bridges, two states, one island, since the course crosses the river repeatedly between Illinois and Iowa, linking Moline and Rock Island with Davenport and Bettendorf
Few American marathons route runners across an interstate river multiple times in one race, and the flat, scenic course has made it a Boston Marathon qualifier that also draws competitive East African fields
Kenyan runners hold both the men's and women's course records
The weekend bundles a full slate of distances, from a marathon relay to a kids' micro-marathon, so families and serious racers share the same course on the same day
The race maintains a long-running Corporate Challenge
where local company teams compete against each other across the weekend's events
and it has built a signature identity around its bridge-and-river route rather than a single ceremonial custom
Pace teams and an elite-athlete program that has drawn a steady stream of top Kenyan finishers have become an established part of race weekend
and the marathon's Boston Qualifier status has made it a recurring goal race for regional qualifiers year after year

Typical late-September Midwest running attire: shorts or capris, a technical short-sleeve or long-sleeve shirt, and a light jacket or arm sleeves for a cool morning start that often warms up...
Quad Cities Marathon is easier when spectators give competitors, vehicles and staff room to work.
