The ITU World Triathlon Series is an innovative series that allows the world’s top triathletes to compete head-to-head on an ongoing basis. Expanding upon the previous single-day World Championship, the format features ten world-class events and an exciting Grand Final. The ITU Series kicks off in Abu Dhabi and makes its way to the City of Chicago for the Grand Final. Chicago joined the series in 2014, marking three consecutive years that the United States has hosted a top-level World Triathlon Series race.

The Chicago course features a 2-lap, 1.5k swim, an 8-lap, 40k bike, and finished with a 4-lap, 10k run.
