The City of Lake Saint Louis (LSL) Parks and Recreation Department is proud to present the oldest organized triathlon event in the St. Louis metropolitan area. This event has proven to be the most popular Triathlon event in the area as it has filled the last ten years with participants who traveled from all over the country. The open water swim and rolling hills make this a challenging, but very enjoyable event to participate in. USA Triathlon Sanctioned and competition rules will apply.

2021 UPDATE:

The City is looking forward to the annual Lake Saint Louis Triathlon after two years off.  In 2021 we will offer a short course Triathlon only.
