Carlyle Lake Triathlon

The Carlyle Lake Triathlon, presented by MSE Racing in partnership with Carlyle Lake, the City of Carlyle, Illinois, and the U.S. Army Corps of Engineers, is a multisport event held at Dam West Beach, 801 Lake Road, Carlyle Township, IL. The event offers multiple race formats with swim, bike, and run legs and is sanctioned by USA Triathlon.

Race options include:

  • Sprint Triathlon: 750 m swim / 20 km bike / 5 km run
  • Olympic Triathlon: 1.5 km swim / 40 km bike / 10 km run
  • Sprint and Olympic Aquabike, Duathlon, High School Triathlon, and Relay divisions

The swim uses a rolling beach start at Carlyle Lake. The bike course is described as flat and scenic across the Illinois plains. The run follows rolling country roads and finishes over the spillway with a view of the lake. A portion of race proceeds will benefit NAMI in honor of Jay Orr.

Registration includes a race shirt, swim cap, finisher medal, live results, awards, and a post-race finish festival with music, food, and drinks. Packet pickup occurs the day before the race at Dam West Beach; athletes must show photo identification and may not pick up another athlete’s packet unless competing as a relay team. Packets contain a wristband for transition access, a timing chip, bike and helmet stickers, and a race bib.

The event enforces USAT membership or a one-day pass and applies cutoffs for swim, bike, run, and overall finish times. The organizer follows a no refund policy and may alter or cancel the event for safety reasons. Visit the organization's website for the most recent information.
