Battle of Waterloo only takes place every other year. It is set to take place in 2021 next. If you are still itching to race, check out some of our other events!

Featured in Triathlete Magazine as a bucket list tri, Battle of Waterloo has 10 legs totaling 42 miles that traverse the sprawling Waterloo Recreation Area, one of the most rugged and beautiful parks in the Midwest. You’ll bike paved remote roads, run winding dirt lanes, climb steep trails, and swim across three wilderness lakes… carrying your shoes and swim gear with you the entire time. Don’t have that much time? Try Half the Battle: six legs, 18 miles of the same terrain (OK, less than half, but Half the Battle is a great name!).

The Battle of Waterloo is the real deal: no cargo nets to climb, no pits of mud in your path, no monkey bars to maneuver through. The lake may be ice cold… or it may not. Our only threat of electroshock is a thunderstorm. Lilypad tangles and jungles of aquatic plants are amongst the obstacles you’ll encounter. Battle of Waterloo is you and mother nature and is and you’ll win the battle!

The Battle of Waterloo is a draft legal race; however, drafting with triathlon bikes and/or aerobars is NOT permitted.

Please note that all of the information here pertains to both the full and half-battle.  The only difference is that the half-battle is fewer legs.

>> Wetsuit Rule/Rental

USAT Rule 4.4 Wet suits. Each age group participant shall be permitted to wear a wet suit without penalty in any event sanctioned by USA Triathlon up to and including a water temperature of 78 degrees Fahrenheit. When the water temperature is greater than 78 degrees, but less than 84 degrees Fahrenheit, age group participants may wear a wet suit at their own discretion, provided however that participants who wear a wet suit within this temperature range shall not be eligible for prizes or awards. Age group participants shall not wear wet suits in water temperatures equal to or greater than 84 degrees Fahrenheit. The wetsuit policy for elite athletes shall be determined by the USAT Athletes Advisory Council. The AAC has set the wetsuit maximum temperature for elite athletes at 68 degrees for swim distances less than 3000 meters and 71.6 degrees for distances of 3000 meters or greater. Any swimmer wearing a wetsuit with a thickness measured in any part greater than 5 millimeters shall be disqualified.

Don’t own a wetsuit but want to rent one?

>> Water Safety

Every member of the Epic Lifeguard Team has American Red Cross Waterfront Lifeguarding Certification in addition to basic American Red Cross Lifeguarding Certification. This means that our guards have all taken and passed an additional course in which they received training in the knowledge and skills needed to prevent and respond to emergencies in non-surf, open-water areas. Our superbly trained lifeguards are yet another reason our races are so Epic! Our lifeguards are also able to keep our swimmers safe thanks to our official SUP company, Red Star Board Company. We’re very grateful to have Red Star as part of Epic team.


>> USA Triathlon

This race is sanctioned by USA Triathlon (USAT) therefore all participants must have an annual membership or purchase a one-day membership. These options will be available during the registration process. The annual membership fee is $50 and the one-day fee is $15. To learn more about USAT visit https://www.teamusa.org/USA-Triathlon/.

Because our triathlons are sanctioned by USA Triathlon (USAT), we follow their wetsuit rules. Competitors may wear wetsuits if the water temperature is 78 degrees or lower. USAT rules also state that if the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards.
