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!

We are thrilled to host the 5th annual Innsbrook Kids Triathlon! The race will start at Charette Creek Commons. The bike is flat and fast! Athletes will ride on scenic paved roads partially closed to traffic with plenty of volunteers along the course and turns clearly marked. Then onto the fun run! It is also FLAT and is half pavement, half on a shady gravel trail.
