The International Triathlon Union hosts a 7-city worldwide tour for professional triathletes as well as amateur athletes competing in 5-year age groups. The culmination of the series is the Grand Final where World Championship titles are awarded for both pros and age groupers. This year’s Grand Final was held in London, England, September 11-15. The Grand Final has never been held in an American city, but after a highly competitive round of bidding, Chicago was awarded the Grand Final for September 2015. Chicago Tonight correspondent Elizabeth Brackett has won four World Championship titles and placed second in this year’s London World Championships. She filed this report on what Chicago can expect when it hosts the World Championships in 2015. Watch the web extra video.
