Runners start the out-and-back course for the Leinenkugel’s Pure Water Days Half Marathon the Chippewa Valley Family YMCA on Jefferson Avenue. From there, you’ll head north along Jefferson up to 136th Street and 85th Avenue, where you’ll start a big, counter-clockwise loop with plenty of long, flat stretches and really only one significant uphill stretch — between the 4th and 5th mile markers along 110th Street in nearby Tilden, just outside Chippewa Falls.
