The lay of the land
Wisconsin 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 Milwaukee, Oconomowoc, Madison, and Green Bay.
Races in Wisconsin cross rolling farmland, Great Lakes shoreline on Michigan and Superior, dense Northwoods forest, and the unglaciated, hillier Driftless Area in the southwest. Courses range from flat lakefront road races to rolling forest trail runs through the Driftless hills.
Conditions vary widely by region across Wisconsin, 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.
