TriRock Lake Geneva

Williams Bay

The 4th Annual TriRock Lake Geneva takes place in the fall and is the end of the season triathlon in the Midwest. Conveniently located between Chicago and Milwaukee, the clear, spring-fed water of Lake Geneva will provide scenic views and rolling hills – the perfect ingredients for a very memorable autumn race in the small lakeside village of Williams Bay, Wisconsin. Highlights include a beach start, running past Yerkes Observatory and fun filled finish festival.
