LONDON, United Kingdom — The Professional Triathletes Organisation (PTO) has officially confirmed the return of its Lake Las Vegas T100 Triathlon weekend, set for October 25–26, 2025, in Henderson, Nevada. This year’s event will introduce a dramatic new bike course for amateur racers, set within the breathtaking expanse of the Lake Mead National Recreation Area.
Returning to the scenic grounds of Reflection Bay Golf Club and The Westin Lake Las Vegas Resort & Spa—now designated as the official headquarters of the event—the triathlon will again showcase the beauty and charm of the Lake Las Vegas area.
A highlight of the 2025 edition is the revamped amateur bike course for the 100km distance (comprising a 2km swim, 80km bike, and 18km run). The new 80km bike leg takes riders on a single-loop out-and-back route through Lake Mead, America’s first National Recreation Area. With sweeping desert landscapes, rugged canyons, and serene valleys, the course offers participants a raw and unforgettable journey through the untamed heart of the American Southwest—just minutes from the glitter of Las Vegas. The route promises both visual splendor and physical challenge, with over 3,600 feet of elevation, making it the most demanding amateur course on the T100 circuit in 2025.
The run segment will also see a fresh twist, culminating at the LED-lit T100 finish arch placed waterside at Reflection Bay—a picturesque setting to cap off a grueling race.
PTO CEO Sam Renouf expressed enthusiasm about the changes:
“We’re thrilled to unveil this major course upgrade for Lake Las Vegas in 2025. The inaugural event in 2024 revealed just how special this location is, and thanks to strong local partnerships, we’re now able to bring athletes into the stunning terrain of Lake Mead. It’s an extraordinary venue where the desert meets water in ways few places on Earth can replicate.”
The expansion of the amateur course is the result of close collaboration with local officials, including City of Henderson Mayor Michelle Romero, who played a key role in bringing the T100 series to the area in 2024 and facilitating improvements for 2025.
“Henderson has emerged as a premier destination for sports and entertainment,” Romero said. “Last year’s T100 drew a global audience and gave amateur and elite athletes alike the chance to compete in one of the most striking backdrops in the country. We’re excited to welcome the triathlon back and showcase our city to the world once again.”
In addition to the marquee 100km races, the weekend will also feature open water swims of 2km and 4km in the calm waters of Lake Las Vegas.
The 2025 T100 Triathlon World Tour kicked off earlier this month in Singapore (April 5–6), where Great Britain’s Kate Waugh and New Zealand’s Hayden Wilde claimed victories in sweltering conditions. They currently lead the T100 “Race to Qatar” rankings. The next stop on the tour lands in San Francisco on May 31, where the world’s top 20 female and male triathletes will take on the legendary Escape from Alcatraz Triathlon—a bucket-list challenge for amateurs and professionals alike.
