Chicago

Chicago's running scene centers on the flat lakefront—the Chicago Marathon follows Lake Michigan's shore for 42km with minimal elevation change, and Lakefront Trail parks like Grant Park host countless local 5Ks year-round. Cyclists dominate the same waterfront corridor but venture inland to rolling terrain; Le Tour de Shore follows the Michigan shoreline for 161km, while serious riders push into the Dunes 50km east near Indiana for dune climbs and forest singletrack.
