Runners take your marks at the Chicago Triathlon August 25-27, and stay at the nearby and affordable LaQuinta Inn Suites in historic Hyde Park!

The Chicago Triathlon is actually a group of competitions. Race weekend consists of five stand-alone triathlons, including the Life Time Kids Tri Chicago (ages 7-14, two distances), Chicago Tri Super Sprint and the Transamerica Chicago Triathlon sprint and international races.

Competitors can race as individuals, as part of a relay or by teaming up with one of our official charity partners. The Triple Challenge is the Chicago Triathlon’s sixth event, consisting of three races unto itself. USA Triathlon membership is required for all races.
