The Belfast City Marathon has been postponed due to the coronavirus, organisers said.
The marathon is now scheduled to take place on Sunday, September 20, while the Belfast City Half Marathon will now take place on Sunday, February 28 next year.
John Allen, chairman of Belfast City Marathon Ltd, said the world is in an "unprecedented situation" and that their "fundamental priority is the health of everyone".
"As a Board of Directors we understand that you will all have many questions and would ask that you please bear with us as we work through the logistics as we prepare for our new scheduled dates," he added.
"The situation is disappointing for you all after your hard weeks of training and efforts of fundraising, but we know we can stay strong and gather to celebrate your achievements on the rescheduled dates."
