    I TRI, THEREFORE I AM! ELEVEN YEAR ANNIVERSARY!

    Join us on Saturday, July 25, 2026 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 11th year since re-establishing the triathlon in 2015. Over the past 11 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!

    Buena Tierra Run Club emerged from a simple revelation. After co-founder Patrick ran through Chicago's Latino Pilsen neighborhood, he knew Milwaukee needed a space where Latino runners could gather, celebrate, and reshape the health narrative in their community. Founded in November 2023, what started with seven people at a first run has grown into a movement of more than 250 runners. Now they gather regularly at Milwaukee's Zócalo Food Park, building a community bound by movement, pride, and the spirit of the Southside. Every run is free and open to all, a chance to inspire the next generation and rep Milwaukee in a way that truly speaks to you.
