TBK Bank Quad Cities Marathon

The TBK Bank Quad Cities Marathon is held annually on the fourth Sunday in September, starting and ending in downtown Moline, Illinois. The course crosses three bridges over the Mississippi River, passes through four cities in two states, and traverses Arsenal Island. Voted best marathon in Illinois, this scenic race along the mighty Mississippi River has been a Midwest running tradition since 1998. The marathon offers a 5-person relay option alongside the full marathon, half marathon, 10K, and 5K.

Late September in the Quad Cities ranges from 10-22C (50-72F). Pleasant fall running weather along the river. Possible wind on bridges.
