About the race

The CORE Indoor Sprint Triathlon is an indoor multisport event held at the CORE Fitness and Aquatic Complex on the Lemont Park District campus in Lemont, Illinois. Each athlete completes three timed segments: a 10 minute swim, a 15 minute bike effort on a Keiser spin bike, and a 15 minute run on a Precor treadmill. Total distance traveled by each athlete is measured at the conclusion of the event. Heats are organized with four to five competitors and start at regular 20 minute intervals.

Athletes are asked to arrive 30 minutes before their assigned heat time for check in. There is no race day registration and event capacity is limited to 60 participants. Participants receive an event t shirt at check in. Recommended items to bring include a swimsuit, towel, lock for personal items, athletic shoes for the bike and run, and any hydration or fuel such as water, sports drinks, or energy gels.

The CORE is not responsible for lost or stolen items. An awards presentation takes place after the last heat, with awards for the overall event winners and first and second place male and female finishers in each age division. Visit the organization's website for the most recent information.
