The Dublin Marathon has been cancelled for the first time in the event's 40-year history.
The race was sold out and was scheduled to take place on October 25 - but won't be held until next year following today's announcement.
Organisers of the marathon explained that entries for this year's race will remain valid for the 2021 marathon.
Refunds will be available for those who don't wish to take part next year.
Race Director Jim Aughney said: “We know this is extremely disappointing for all runners, especially those who secured marathon entries.
"We made the difficult decision in the best interest of the health and wellbeing of all those involved in making our events such a success from runners, supporters, volunteers, sponsors, to suppliers.
"We explored many alternatives for running the events safely but ultimately none were viable.”
Aidan Power - from race sponsors KBC - added: “Whilst this decision will disappoint the many loyal runners and spectators of the KBC Dublin Marathon, it is essential that public health and wellbeing takes priority over everything else.
"This is the right and responsible decision that the event organisers of the Dublin Marathon have taken and KBC as sponsors remain committed to its support and look forward to welcoming runners again in 2021.”
