How the Dublin Marathon affects Dublin's roads

Dublin Marathon road closures, 30th Oct 2022

Group of Marathon Runners

Dublin Marathon is a huge event for the city, and certainly an exciting one. Crowds gather in their scores to watch the 20,000 marathon runners as they stampede through the streets (some dressed normally, others in full costume). But all this excitement can result in road closures. Below, you can find out more about when the marathon is and the roads/areas that could be affected.

When is the Dublin Marathon?

The Dublin Marathon is due to take place on 30th October 2022, with an estimated start time of 08:45am. Runners are expected to finish within seven hours, meaning the race should finish around 5 or 6pm (depending on their start time).

The Dublin Marathon Route

The Dublin Marathon is due to start on Fitzwilliam Street Upper, near to Fitzwilliam Square. The marathon is one continuous lap, meaning you will finish on Merrion Square North, not far from where you started.

The route takes you out of Dublin city centre, over the River Liffey via the James Joyce bridge. From here, you will head to Phoenix Park, passing near to Dublin Zoo, and continue through the park for around two miles (Miles 5 and 6). You will leave the park via Chapelizod Road, recross the Liffey via Chapelizod Bridge and continue along Inchicore Road, past Dublin’s famous Kilmainham Gaol (Mile 11).

Then you will travel over Dolphins Barn bridge towards Brickfields Park. The route continues through the city roads, towards Bushy Park (Mile 17). From here, you will carry on running along a series of roads until eventually you will reach Roebeck Road. This will take you around the perimeter of University College Dublin (Miles 22 and 23). Next, you will pass Elm Park golf course and carry on north along Northumberland Road and Mount Street Lower to reach your final destination, after 26.2 miles, to Merrion Square for the finish line.
