Thousands of people are taking to the streets of Belfast this morning as the annual city marathon gets underway.
Beginning from 9am, the 42.1km race will take runners across east, north, west and south Belfast, before finishing in Ormeau Park.
It passes historic landmarks including City Hall and Parliament Buildings at Stormont.
A relay and wheelchair race will follow the same route as the marathon, and there is also an 12.8km walk.
This year around 4,500 runners are competing in the marathon and wheelchair race, and 9,000 in the relay.
The fastest runners are expected to finish by 11am with other participants completing the marathon in the hours afterwards.
A number of road closures are in place from 6am until approximately 4.30pm, with motorists advised to check their routes before travelling.
This year's race will be broadcast live in full online for the first time by BBC Northern Ireland.
Commentary on the race will be provided by Northern Ireland Commonwealth Games athlete Katie Kirk and BBC presenter Mark Simpson.
Last year's men's marathon was won by Irish Olympian Paul Pollock, in a time of two hours, 16 minutes and 13 seconds.
