The Mabie Mile set to take place on Saturday has now been pushed back to Saturday March 18.
A statement from Dumfries and Galloway Council said: “We’re sorry for any inconvenience caused by postponing the event but the health and safety of participants must obviously be paramount. ”
Runners already registered for the event will be emailed by the council’s Nithsdale Active Schools and Community Sport Team with arrangements for re-registration.
