A tri for everyone

Carlyle Lake Triathlon

USAT Sanctioned logo.png

In partnership with Carlyle Lake, the City of Carlyle, Il, and the US Army Corps of Engineers, MSE Racing is proud to bring to you the Carlyle Lake Triathlon. This event replaces the CAPEX Triathlon from prior years.

Experience an exciting rolling beach start for the beautiful Carlyle Lake swim, transitioning to a flat, scenic bike course over the planes of Illinois.  The run takes you on rolling country roads to finish coming over the spillway at the end with a view of the largest man-made lake in Illinois. With multiple distance options to choose from, there is sure to be an event for every type and skill level of triathlete.

You'll revel in the famously flat and fast roads of Carlyle, the view over the spillway of the dam, and much, much more!

TIME: 3:30pm - 5:30pm (try and make this one)

You CANNOT pick up someone else's packet unless you are doing a relay. Make sure you bring your photo ID.

RACE PACKET: There will be 5 specific items to be aware of -

  1. Wristband: There will be a wristband with your race number. These must be worn to access transition on Saturday and Sunday. If you misplace this band, you will need to secure a new one prior to entering transition..

  2. Timing Chip: You will receive your timing chip when you pick up your packet at the expo on Saturday. DO NOT FORGET THIS ON RACE MORNING. You will wear the timing chip on your left ankle with the chip portion facing out. This is how you will be timed. NO CHIP = NO TIME = NO RESULTS.

  3. Bike Sticker: place this on your bike, usually the seat post is the best place or the top tube.

  4. Helmet Sticker: place this on the front of your helmet.

  5. Race Bib: You are only required to wear your bib while you are on the run. It should always be forward-facing and visible. You can affix it to you using safety pins or a bib belt

USAT, or USA Triathlon, is the national governing body of the sport of Triathlon. Sanctioning an event through USAT means the race is provided insurance for its athletes, race coordinators, and volunteers. As a sanctioned triathlon, all athletes are required to either be an annual USAT member or purchase a one-day membership pass. If you are currently a USAT member, please make sure to bring your proof of membership when you pick up your packet. If you do not bring this proof, you will be
charged the one-day membership fee. If you are not an annual member, you will need to purchase a one-day membership (to insure you as a triathlete) before you are able to pick up your packet. One-day membership will be collected when you register online. A USAT Official will be at the event and will be enforcing all USAT rules. It is strongly suggested you visit the USAT website for the complete list of rules and review. Race management reserves the right to remove an athlete from the course and DNF the athlete if course officials determine there is no possibility of an athlete finishing the given discipline (swim, bike, run) before the posted cut off times based on an athlete’s location, time, and average speed up to that point.



There may be a photographer on site capturing pictures of the event. Since this is a public event, we reserve the right to post photos on our social media or agency website. Photos may also be used in promotional materials.


Last day to register to guarantee a race shirt is August 22, 2024.

There is NO rain date, We Go Rain or Shine. In case of inclement weather,
management reserves the right to cancel/alter/modify the race/course for safety concerns. In any case there will be No Refunds of race entry fees. Each athlete must accept any such risk of their entry fee paid. There is no complementary race entry to a future race. All monies collected are used to develop and produce the event, including all race supplies, staffing, and administration. We pledge to make every effort to produce a fair, safe, and exciting event for all. Any decision we make to go forth with the
race is based on the overall event safety. We have a strict NO REFUND policy.

Relay triathlon is a WONDERFUL way to experience a triathlon if you are not ready to run the whole thing, if you are not capable of competing in a specific leg, or if you just want an opportunity to share something unique with friends or family. A triathlon relay can be done with 2 or 3 people. The team can consist of all male participants, all female or mixed. Each person does 1 or 2 legs of the race. The timing chip will have a Velcro
strap on it and is handed off from one athlete to the next in transition. All athletes receive full swag and finisher medals.

Spectators, the unsung hero of the triathlon. Without family and friends there to cheer us forward, the rigors of our sport would be far more difficult. MSE Racing is dedicated to ensuring that these vital portions of our triathlon family are given the opportunity to enjoy themselves while they wait for the next opportunity to see you fly by.
MSE Racing is proud to provide the following amenities:

  • Sign making craft table for kids

  • Yard game section

  • Food trucks/food options available for purchase so that spectators can have something to eat

  • Music for additional entertainment

  • Vendor and club booths available to visit

So, bring out those cow bells and noise makers for a fun day at the race!


Reservation block available until August 9th but will likely sell out before then. This is within walking distance to the race start! Call the hotel and mention that you are with the Carlyle Lake Triathlon & MSE Racing.
