The lay of the land
Iowa runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in September, August, and October, with races most often held in Des Moines, Bettendorf, Iowa City, and Ames.
Races in Iowa cross gently rolling farmland and prairie across most of the state, with steeper river bluffs along the Mississippi to the east and the distinctive Loess Hills rising along the Missouri River to the west. Courses are generally rolling rather than flat, with real climbs near the river bluffs.
Conditions vary widely by region across Iowa, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
