The Phoenix Energy Belfast City Marathon and Team Relay starts Sunday from Stormont Estate via Prince of Wales Avenue at 9am. The course crosses all areas of Belfast and ends in Ormeau Park.

Police advise motorists to expect disruption due to a road closure order approved for organisers under legislation. Roads begin closing wholly or partially from 6am and fully reopen by 4.30pm.

Spectators will line the route. Drivers must follow closure notices and use diversionary routes.

Motorists should check routes in advance and allow extra time for travel across the city.
