The 100 Club Challenge is a special race within a race competition during the Transamerica Chicago Triathlon weekend, held each August in downtown Chicago. Originally known as the First Responders’ Competition, the program began in 2007 as a friendly wager among seven members of the Chicago Police Department and the Chicago Office of the FBI. Since then, the competition has hosted more than 1,000 participants from more than 24 agencies across the country. The Transamerica Chicago Triathlon is the world‘s largest multisport event, having welcomed more than 250,000 triathletes across the finish line since 1983. This is truly Where the World Comes to Race.
