World Triathlon, the sport’s governing body, has agreed a two-year partnership with the Swiss luxury watchmaker Maurice Lacroix.
The company will serve as the official timekeeper to the World Triathlon Championship Series.
The deal comes into effect for the opening round of the 2021 season, which takes place in Yokohama in Japan on 15 May.
Hailing the new partner, Marisol Casado, the president of World Triathlon, said: "We are so pleased to announce that Maurice Lacroix has been appointed the Official Timekeeper of the World Triathlon Championship Series. We are delighted to welcome such a prestigious new partner to the World Triathlon family and to work with them during this incredibly important Olympic and Paralympic year.”
Meanwhile, the Ironman Group, the organiser of long-distance triathlons, has named St. George in the US state of Utah as the host of the 2022 North America Championships.
It will also stage the event in 2024.
Next year's full-distance Ironman triathlon event will take place on 7 May.
St. George last hosted a full-distance race in 2012, and was due to do so again in 2020 only for the event to be cancelled because of the coronavirus pandemic.
St. George will continue to host Ironman 70.3 events in the years between the full-distance event.
