Open Water Swim Series

Get Wet and Come Swim with the Big Sharks Every Saturday, May through June!

What it is: Get comfortable in the open water and/or practice you swim technique in a lake within the St. Louis Metro area! Each Open Water Swim will take place every Saturday Morning from May 3rd through June 28th. Lake will be open for participants from 8:00 am – 10:00 am.  Come join us each Saturday and swim as many laps as you like. For sighting and safety we will have buoys in place. Each OWS session will be staffed by Backyard Lifeguards and be accompanied by additional programming. Please note- this is a USAT insured event, as is the Triathlon and the Splash and Dash- participants will be required to purchase a 1-Day or Annual USAT license that is not included in the fee to swim. If you plan on doing several OWS events- please consider the annual license.

Where: The lake is located at New Town in St. Charles and is a very similar swim course as used in the Motion Orthopaedic Newtown Triathlon. The perimeter course is .62 miles and in most areas you can touch the bottom.

Cost: $15.00 per session. Special wetsuit rental rates is $10.00 per session (2 rental payments can be applied to purchase). Fee structure covers venue, event sanctioning, professional lifeguards, equipment, programming and support.

Support: Big Shark Bicycle Company will have a rental wetsuit fleet on site every week. For athletes who would like to run or ride after the OWS we will be providing an on site bicycle mechanic as well as a ride and run leader for post swim brick training.

Post swim brick training: Each and every Saturday following the scheduled programming we will have run and ride leaders from the St. Louis Tri Club to complete your brick training. We will meet at the registration tent at 10:30 at which point we will divide into our respective run or ride groups. All abilities welcome.
