Lake Country Triathlon

City Beach 324 W. Wisconsin, Oconomowoc, WI 53066

Started in 1983, the Lake Country Tri was one of the first and largest tris in Wisconsin. The race would sell out every year but eventually changed hands and disappeared in 1993. In 2015, Silver Circle Sports Events, LLC brought the event back and has sold out each year.

The course starts at Oconomowoc's City Beach on Lake Lac Labelle followed by a bike ride through Lake Country's beautiful countryside.  The run is right down Wisconsin Avenue with athletes with spectators cheering you on.
