About America's Race

Leon’s Triathlon is a historic Chicagoland triathlon founded in 1983 by Leon Wolek. Known as “America’s Race,” it is dedicated to honoring and supporting U.S. service men and women, especially injured military veterans. The event welcomes both civilians and military participants, creating a meaningful and patriotic race experience for all.

Hosted each June in Northwest Indiana, just 20 minutes from downtown Chicago, Leon’s is recognized as a beginner-friendly triathlon with a flat, fast, and traffic-free course—making it an ideal race for first-time triathletes as well as experienced competitors.

With a long-standing legacy in the sport, Leon’s pioneered the first National Amateur Championship, which continues today under USA Triathlon. In 1996, Leon’s also hosted one of the first Military Championships in the sport, both of which were televised on ESPN worldwide.

Swim

The Swim Course is held in Hammond’s Wolf Lake, allowing athletes to compete in open water without worrying about any possible waves or currents.

Bike

The Bike Course is a newly paved traffic free bike course on a gold star memorial highway, giving athletes the chance to focus on fast bike splits.

Run

And, we save the best for last with a super flat and breathtaking Run Course around beautiful Wolf Lake.

Canines

Race with your dog. For those interested, we have added a canine version of the race to our events.

2021 Obstacle Course Race

In 2021 Leon added an obstacle course race to honor the 20th anniversary of the September 11th attacks on our country. With the addition of the obstacle course race, we have rebranded the triathlon to include the sister obstacle course race, and we are moving forward as Leon’s Heroes.

While growing up Leon didn’t have Superman or Batman as a hero, it was his father and military buddies at the American Legion Post 454 in New Chicago, IN whom inspired him. Leon’s Heroes are the men and women who put their lives on the line to defend our nation and constitution. We aim to create a feel of patriotism anywhere we go.
