IRONMAN 70.3 Comes to Little Elm & Denton County
Get ready to witness an incredible display of athleticism as the IRONMAN 70.3 Dallas–Little Elm triathlon makes its momentous debut this spring — Sunday, March 15, 2026.
This exhilarating event will bring over 2,700 athletes to the picturesque shores of Lewisville Lake, giving Denton County residents a front-row seat to one of the most coveted and grueling endurance challenges of the year.
The race boasts an impressive 70.3 miles of competition, featuring a 1.2-mile swim at Little Elm Beach, the largest beach in North Texas. Spectators will enjoy a front-row view as athletes dive into the brisk waters and emerge from their swim, perfectly positioned for cheer zones along the coast.
The excitement continues on land with a scenic 56-mile bike course that winds through the charming landscapes of North Texas, showcasing open roads and breathtaking lakeside vistas.
Rounding off the challenge is a 13.1-mile run that loops through Little Elm’s nature trails along a smooth, spectator-friendly route where family and friends can support their athletes multiple times.
This race not only promises to be a thrilling competition, but it also offers qualifying spots for the prestigious 2026 IRONMAN 70.3 World Championship in Nice, France, making it a premier event for serious triathletes.
As the host town, Little Elm offers a laid-back, hospitable vibe complemented by beautiful lakefront parks and welcoming community atmosphere. Local partners, including the neighboring towns of Celina, Frisco, and Prosper, will come together to create an unforgettable experience for athletes and spectators.
For Denton County residents, this is more than just a race — it’s an outstanding opportunity to rally together, cheer on fellow athletes, and enjoy a full day of vibrant festivities. Mark your calendars and prepare for an unforgettable day of competitive entertainment.
