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.
