Endurance Grid lists 305 running races in Wisconsin, from September 2026 to October 2027 across 138 cities.
The running race calendar in Wisconsin is busiest in October, September, and November, with races most often in Milwaukee, Oconomowoc, Madison, and Green Bay.
Organized running races are one of the most accessible entry points into endurance sports. There’s a distance for every fitness level and a community at every start line. Distances run from 1-mile fun runs and 5Ks up through the 10K, half marathon, and marathon.
Most races are timed and chip-scored, with a mass or wave start and aid stations along the course. Big-city races keep the noise going the whole way; smaller races give you long stretches where it’s just you and the miles.
