This Sunday, April 30th, the Mash Direct Belfast City Marathon, Team Relay and 8 Mile Walk will set off from the Stormont Estate (via Prince of Wales Avenue) at 9am onto a course which will cross all areas of the City before finishing in Ormeau Park.
A significant number of spectators are expected to line the route.
In line with legislation the Marathon Organisers have applied for a road closure order and road users should expect some disruption throughout the duration of the race.
Motorists are asked to adhere to road closure notices and make use of the diversionary routes.
Roads will start to close wholly or partially from around 6.00am and will fully reopen by 4.30pm.
On Sunday afternoon there will also be a series of Parades in Belfast which will impact on traffic volume.
Motorists are asked to check their routes before travelling and allow plenty of time for journeys across the city throughout the day.
