Join us on Saturday, July 31, 2027 for the Lake Country Triathlon, one of the Midwest premiere endurance challenges. Located in the heart of beautiful Lake Country, Wisconsin. The Lake Country Triathlon offers an amazing race experience that begins with a swim in the clear waters of Lac La Belle, an incredible scenic ride through the rural glacial landscape of SE Wisconsin, and a run through the charming community of Oconomowoc.
This year is our 12th year since re-establishing the triathlon in 2015. Over the past 12 years, we've seen athletes from nearly every state, Canada, and even Europe. We are the perfect setting for the first time triathlete and provide challenging competition for the world's best elite triathletes. We're hoping this year will be our largest and best Lake Country Tri yet and we hope you'll join us in July!

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it’s the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Three sports, one race — swim, bike, run in sequence, with transitions that are a discipline of their own.
Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
