  Rising from the shores of Lake Michigan, Chicago is a city defined by its towering skyline, deep-seated sports legacy, and an unmistakable Midwestern grit. From the historic steel of the "L" trains to the vibrant energy of its world-class waterfront, the "Windy City" offers a high-octane atmosphere where legendary architecture meets a community that prides itself on hard work and resilience.

  The event takes over the expansive exhibition halls of Navy Pier, providing a high-energy indoor environment with breathtaking views of the lake. Over three days, competitors will face the signature 10-zone, 5km course, featuring everything from the high-stakes Elite and Age Group heats to the heavy-duty Ruck challenge. Whether you’re grabbing a partner for 2-person teams, gathering a squad for the 4-person format, or braving the grueling DEKA FIT Ultra, Chicago offers a world-class stage to test your mettle.
