  Come and race in the most beautiful venue that we have near St. Louis! Innsbrook Resort is full of breathtaking views, lakes, and wooded acres. We are starting at Lionshead Beach on Lake Aspen! It is a gorgeous, sandy beach start. Swim in the lake, bike on gentle rolling hills surrounding the resort, and run on part gravel, part pavement as you take in the scenery. We offer sprint and Olympic distances with Aqua bike and relay options!
