The International Triathlon Union (ITU) Multisport World Championships in Almere have been postponed to 2021.
Competition was originally scheduled in the the Dutch city of Almere from September 4 to 13, but has been moved to next year due to the coronavirus pandemic.
Dates are to be confirmed at a later stage.
The Multisport World Championships in Townsville in Australia have subsequently been moved to 2022, while Ibiza in Spain will now host the event in 2023.
"This has not been an easy decision to take for any of us, but considering the situation facing athletes around the world, many of them with insufficient access to training due to lockdown, and with travel restrictions still applying in many countries, we all agreed that the best option for all concerned was to move the events forward by one year," said ITU President and International Olympic Committee member Marisol Casado.
"The local organisers in Almere, Townsville and Ibiza have worked tirelessly with our staff to continue with all the preparations, and exploration of the best options for the future.
"This agreement between us all will ensure that we can provide events in the next three years with the excellence and success that we have enjoyed on previous occasions - perfect scenario for athletes, friends and family to enjoy 10 days of multisport and triathlon at its best."
