Athletics Ireland will host the National Senior Track and Field Championships over successive weekends at Morton Stadium in Santry this month, in response to Covid-19 restrictions.
The Irish Nationals have taken place every year since 1873, making them the longest continuously-running athletics championships worldwide.
The event was originally scheduled for June, then postponed to August in anticipation of the expected rise in numbers allowed to attend outdoor gatherings from 200 to 500 people under Phase 4 of reopening.
That has now been delayed until 31 August, at least, and, given the ongoing uncertainty, the Irish governing body has decided to split the programme of events over four days - on the weekends of 22-23 August and 29-30 August.
Over 720 entries have been received for the various events and a full programme is expected to be announced today.
Athletes travelling from countries that are not on the Government 'green list', including Britain, will have to restrict their movements for 14 days before competing.
