The British Athletics Championships have been rescheduled for 8-9 August because of the coronavirus pandemic.
The event, which normally acts as trials for the Olympics, was meant to take place on 20-21 June in Manchester.
But with the sporting schedule being increasingly wiped out, British Athletics has been forced to push it back.
However, in a statement, British Athletics added that it expects all of its events to go ahead this year.
That includes the Anniversary Games in London at the start of July and the Grand Prix in Gateshead the following month.
The Manchester event would act as trials for the forthcoming European Championships, still scheduled to take place in Paris from 25-30 August.
However, the statement added that British Athletics will "continue to provide updates concerning the competition calendar" and will "adhere to all government advice and guidelines to ensure the safety of those involved".
The Tokyo Olympics, scheduled for July this year, have been pushed back to 2021 and Diamond League meetings in Stockholm (24 May), Naples/Rome (28 May) and Rabat (31 May) have been suspended as the virus continues to affect the sporting calendar.
There is a suspension on all domestic athletics in the UK until the end of May.
