The head of Paris' bid for the 2024 Olympics has branded Tokyo's original 2020 Games proposal "a fairy tale" and believes the French capital can avoid the kind of after-the-fact revisions bogging down Japan's organizers.

Paris is competing with Los Angeles and Budapest for the right to host the 2024 Games, with a decision set to be taken in Lima on Sept. 13, 2017.

Tokyo was awarded the 2020 Games in 2013 after presenting a bid that promised to keep most of the competition venues within 8 km of the athletes' village. But organizers have since relocated several venues outside the city in a bid to cut skyrocketing costs.
