Geneva Lake is "one of the Great Blue Lakes of the World." Geneva Lake has been a Mecca for tourists since the late 1800's. The lake is nine miles long and 170 feet deep, spring fed, and clear. The course is a challenging and picturesque route around the perimeter of Geneva Lake. Geneva Lake is located in the glaciated hills of southeastern Wisconsin. The scenic views and unbelievable hills combined with a final run on an ancient Indian trail provide the ingredients for a very memorable marathon. The marathon will be both demanding for the best runners and an opportunity not to be missed for those runners looking for the ultimate marathon challenge. The USAT & F certified course starts in downtown Lake Geneva, Wisconsin on the lakefront bridge and follows a southwesterly route around the lake through the Villages of Fontana and Williams Bay, then proceeding east along the lake back to Library Park in Lake Geneva.
