Sebastian Coe, president of athletics' world governing body, made it clear on Thursday that all world championships events in the summer of 2025 will be staged in the host city of Tokyo.
At last year's Tokyo Olympics, marathon and race walk events were relocated to Sapporo due to concerns over the Japanese capital's extreme summer heat, a move that angered Tokyo Gov. Yuriko Koike.
While expressing his concern over global warming, Coe told Kyodo News during an interview in Tokyo that there would be no such arrangements at the world championships.
