(FILES) This photograph taken on August 20, 2023, shows the starting line dedicated to the swim familiarisation event of the 2023 World Triathlon Olympic Games Test Event floating on the Seine river with the Eiffel Tower in the background ahead of the mixed relay 2023 World Triathlon Olympic Games Test Event in Paris. From August 17 to 20, 2023, Paris 2024 is organising four triathlon events to test several arrangements, such as the sports operations, one year before the Paris 2024 Olympic and Paralympic Games. The swim familiarisation event follows the cancellation on August 6 of the pre-Olympics test swimming competition due to excessive pollution which forced organisers to cancel the pre-Olympics event.
