The St. Luke’s New Town Triathlon has become one of the most popular triathlons in the Midwest. Originally a biathlon started many years ago, the event evolved into the John Howard New Town Duathlon, and now in its current format as an ‘almost’ Olympic distance triathlon.
This year the distances remain at a .62 mile Swim, 20 mile Bike and a 4 mile Run for the Long Course, and .3 mile Swim, 17 mile Bike and a 2 mile Run for the Sprint Course. The Kid’s Triathlon and EXPO will be held on Saturday, July 11th and the main event will be on Sunday, July 12th, 2026.
Set in New Town, St.Charles, the venue is tailor made for a fast race. The flat course profile makes this event the perfect race to open up full bore or try the sport of triathlon for the first time.

We will have a couple of buoys for use at the clinic session, but not full access to the triathlon swim courses because the park will be open to the public that day.
This event is open to anyone at any level. We offer a special discounted rate for athletes participating in the Lakeside 370 Triathlon if you bundle and purchase the Open Water Swim Clinic Session when you register for the 370 Lakeside Triathlon.
During the session lifeguards and volunteers will be in the water to ensure the safety of the participants, there will also be buoys setup in the water to practice sighting. After the swim, please stick around for the MSE Lakeside 370 Triathlon Expo.
