IMT Des Moines Marathon

The IMT Des Moines Marathon, first run in the early 2000s and now one of Iowa’s premier fall road races, has grown into a beloved Midwestern tradition that draws both local runners and out-of-state competitors. Held in mid-October when the river valleys and tree-lined streets are at their peak color, the race benefits community causes and showcases Des Moines’ evolving downtown. The event weekend also includes a half marathon, relay and various youth and community races, creating a festival-like atmosphere that makes it a destination for runners of all abilities.

The course takes runners on a varied and scenic tour of Des Moines, with stretches along the Des Moines River, the scenic riverwalk and numerous city parks. Runners pass iconic city landmarks and neighborhoods — including the State Capitol area, the East Village, downtown arts and entertainment districts, and segments that showcase Gray’s Lake and riverside trails — blending urban architecture with leafy, park-like vistas. Many participants cite the well-supported course, enthusiastic local spectators, frequent aid stations, and live music along parts of the route as highlights that help carry them through to the finish. The race is USATF-certified and serves as a Boston Marathon qualifier, with accurate chip timing and race-day amenities aimed at delivering a fast, enjoyable experience for competitive and recreational runners alike.
