Big Chill 2027

The Big Chill is the coldest event in Wisconsin’s Winter Run Series, a six-race winter schedule focused on Milwaukee and its nearby suburbs. It takes place in South Milwaukee, offering participants a choice between a 5K or 10K. Both races begin in the morning and are suitable for families and dedicated winter runners alike. The broader Winter Run Series is promoted as Wisconsin’s largest running series, with the Big Chill serving as its mid-winter challenge. The course details are straightforward, not technical, but the race’s character is evident: prepare for significant cold, bring a warm coat for before and after the run, and anticipate the common runner’s adage holding true more than ever — the faster you run, the warmer you will be.
