Quad Cities Marathon, Half Marathon, 5K & Relay

Sunday, September 22, 2024 • Moline, IL • Course Map

There’s a wealth of distances and events to choose from at this race — including a full 26.2-mile marathon, a 13.1-mile half marathon, a 5K run/walk, a five-person marathon relay, a one-mile walk and even a children’s “micro” marathon that features three distances.

It’s the longer-distance races, however, that offer the scenery this running event has become known for — big, expansive views of the Mississippi River, along with a course that takes runners through Arsenal Island that sits in the middle of the river, as well as through the city streets of Davenport and Bettendorf, Iowa, as participants run through two states over the course of the race.

The half-marathon event shares the same starting line as the full marathon — on the Moline, Ill., side of the river, between the I wireless Center and the Radisson Hotel — as well as many of the same views along the course, which takes runners across bridges and through many of the same scenic areas as the full, including beautiful views of the Mississippi River across Interstate 74.

The course is mostly flat and fast, with the exception of a mild uphill around the third mile and the ramps for the bridges. Organizers note that while there’s no official time limit for the half marathon, runners are strongly encouraged to finish within 4 hours.

At the race’s 2016 running, more than 3,800 runners and walkers crossed the finish line in the individual races combined, including 1,900 finishers in the half marathon alone — officially called the Mel Foster Half Marathon.

    If you like warm and humid races, this one is for you. The course itself isn’t fancy. Hilly parts are in the first four miles. After that, it is mostly flat. Plenty of water stations and it was well marked. Nice atmosphere and good finish area goodies. The expo was small. Shirt was blue this year, but it didn’t fit. My XL was like a L. Could be a one time issue, but it was disappointing.
    Would I run this again, probably not.
