Thousands are getting ready to take part in the Dublin marathon tomorrow, with road closures affecting traffic and public transport across the city. 

More than 22-thousand people will be running, jogging and walking the 26-point-2 mile course, which starts on Lesson Street Lower.  

Thousands are also travelling to Dublin from 50 countries to take part in tomorrow's event. 

Road closures are already in place in parts of the city, with warnings some public transport routes will be impacted. 

The Route

Merrion Square South will remain closed until 2pm on Monday, while all other roads are scheduled to reopen by 8pm on Sunday. 

Starting on Leeson Street Lower, the marathon will move through St Stephen’s Green South up to Kevin Street Upper. 

From there, it will head straight along Patrick’s Street, passing onto Nicholas Street, Christchurch Place, Lord Edward Street and Parliament Street. 

There the route turns onto the quays, continuing on until the James Joyce bridge, at which point it will move along Blackhall place through Stoneybatter.

Runners will then be directed along Manor Street, Aughrim Street and the North Circular Road to the gates of the Phoenix Park. 

After passing through the centre of the park, participants will continue along the Castleknock road.

This marks the farthest point at which the marathon extends into North Dublin. 

The route then turns West on College Road, continuing along Tower Road until re-entering the Phoenix Park at Knockmaroon Road. 

Runners exit the park again at the Chapelizod Gate and continue over Chapelizod bridge, after which they will turn onto St Laurence Road.
