The 2021 IAAF World Championships will be shifted to 2022 to accommodate the re-arranged Tokyo Olympics, World Athletics said on Monday.
The announcement came immediately after Olympics organisers said the 2020 Tokyo Games - postponed because of the coronavirus pandemic - will now take place on 23 July - 8 August, 2021.
That means the world athletics championships that were scheduled to take place in Eugene, Oregon, on 6-15 August, 2021 can no longer be held on those dates.
"We support the new 2021 dates for the Tokyo 2020 Olympic Games
announced today by the Japanese organisers and the IOC," World Athletics
said in a statement.
"This gives our athletes the time they need to get back into training and competition.
"Everyone needs to be flexible and compromise and to that end we are
now working with the organisers of the World Athletics Championships in
Oregon on new dates in 2022 for our World Athletics Championships."
World Athletics said they were also "in discussions" with the
Commonwealth Games Federation, the organisers of the Commonwealth Games
that are currently scheduled to be held In the English city of
Birmingham on 27 July - 7 August, 2022.
The athletics federation said it was also talking to the organisers
of the 2022 European Athletics Championships, which are due to take
place in Munich on 11-21 August.
There has been no decision yet whether to postpone this year's European championships, slated for Paris between 26-30 August.
