With the Mediterranean Sea on one side and the Alpes-Maritimes rising on the other, Nice provides a course unlike any other on the championship calendar, stunningly beautiful, brutally challenging, and unforgettable for athletes and fans alike.

The day begins in the sparkling waters of the Mediterranean before athletes face the legendary bike course, famous for its relentless climbs, technical descents, and sweeping views of the Côte d’Azur. The race will close with a marathon along the iconic Promenade des Anglais, where the energy of the crowd will be as fierce as the heat radiating off the Riviera pavement. It’s a course that doesn’t forgive mistakes, demanding a balance of patience, power, and precision from anyone hoping to wear the crown.

The professional men’s field is loaded, with season standings razor-tight heading into one of the sport’s biggest stages. With so much talent on the start line and the season-long points chase in play, every move on the bike and every step of the run could shape not only the world title, but the championship picture for the year. Of course, the men’s championship in Nice is about more than just the pros. Thousands of age-group athletes from around the globe will line up to test themselves on the same legendary course. For some, it’s the culmination of years of hard work to qualify; for others, it’s the dream of competing on the sport’s biggest stage. The shared challenge, swimming, cycling, and running through one of the toughest and most picturesque courses in triathlon, cements the event as both a personal milestone and a global celebration of endurance sport.
