About the IMT Des Moines Marathon
IMT Des Moines Marathon is Iowa's signature marathon and reaches its 25th running in 2026. The event offers the scale and support of a major regional race while remaining a comparatively accessible fall goal marathon.
Course
The current marathon course starts and finishes in downtown Des Moines and is designed around a flatter, spectator-friendly city route. Long runnable sections support pace goals, while the urban loop keeps crowd and relay activity close.
Race-day weather
Mid-October in central Iowa can be cold, mild, windy, or all three during the race. Open streets make wind direction a more important pacing factor than the flat profile suggests.
