Dublin Marathon 2026: History, Route & Where to Stay
Dublin Marathon 2026: The History, This Year’s Route & Where to Stay in Dublin
There are easier ways to see Dublin than running 26.2 miles around it.
Few, however, are quite as memorable.
Every autumn, thousands of runners take over the streets of the capital for the Irish Life Dublin Marathon. For some, it is an attempt at a personal best. For others, it is their first marathon, the end of months of training or an opportunity to raise money for a cause that means something deeply personal.
For the people lining the streets, it is something else again: one of those rare days when whole neighbourhoods seem to come outside at once.
In 2026, the Irish Life Dublin Marathon takes place on Sunday, 25 October, celebrating the 45th official running of an event that began back in 1980.
If you’re travelling to Dublin to run, support somebody taking part or simply experience marathon weekend in the city, here’s what you need to know.
When Is the Dublin Marathon 2026?
The 2026 Irish Life Dublin Marathon takes place on Sunday, 25 October 2026.
Demand is extraordinary. More than 47,000 applications were received for the 2026 ballot, the highest number in the event’s history. Of those, 17,200 runners secured places through the general ballot, while the overall race capacity is 22,500 once charity, elite, Good for Age and other allocations are included.
That demand doesn’t only affect race entries.
Marathon weekend brings runners, families and supporters into Dublin from across Ireland and overseas, which means accommodation in central Dublin is worth organising well in advance.
From 1,420 Finishers to One of Europe’s Great City Marathons
The Dublin Marathon story begins in 1980.
The race was largely born from the vision of Irish middle-distance runner Noel Carroll, who persuaded the Business Houses Athletic Association to take on the idea of staging a marathon through Dublin.
The inaugural event attracted an entry of around 2,100 people, with 1,420 runners reaching the finish line.
Dick Hooper won that first men’s race in 2:16:14 and would eventually become the only person to win the Dublin Marathon three times. Carey May led the women’s field home in 2:42:11, one of just 40 female finishers in that inaugural race.
Within only two years, Dublin’s running boom had transformed the event. The 1982 marathon attracted more than 11,000 entries. Through quieter periods and subsequent revivals, the race continued to evolve into the international event Dublin knows today.
And yet, despite the growth, the attraction of Dublin Marathon has always been about more than numbers.
It is the people.
The volunteers handing out water. The families waiting at roadsides. The clubs travelling together. The strangers shouting encouragement when someone’s legs are beginning to question every life choice that brought them to kilometre 35.
That’s part of what gives Dublin Marathon its character.
Why 2026 Is a Particularly Important Year
This year’s event is officially the 45th running of the Dublin Marathon.
Although 2026 comes 47 years after the event was established, two editions during the Covid-19 pandemic were held virtually, which is why 2026 marks the 45th physical running.
Organisers are using the occasion to begin the race’s “Road to 50”, building towards the 50th running in 2031.
There’s also a new #EveryBibHasAStory campaign designed to highlight the personal stories behind the runners taking part — something that feels particularly appropriate for an event where so many people are running for reasons far greater than a finishing time.
Charity is a significant part of the event too. By July 2026, more than €1.3 million had already been raised through the marathon’s fundraising campaign, with 208 charities participating, including 110 Irish charities.
What Is the Dublin Marathon Route for 2026?
The 2026 course gives runners a remarkably varied tour of Dublin.
The race begins on Leeson Street, with an initial downhill section towards St Stephen’s Green. From there, runners pass through the historic Liberties and by St Patrick’s Cathedral before climbing Patrick Street towards Christchurch.
The course then crosses towards Dublin’s northside.
At approximately 6km, runners enter Phoenix Park, passing Dublin Zoo and continuing along Chesterfield Avenue. After Castleknock, the route returns through the park before descending towards Chapelizod and Inchicore.
Next comes Kilmainham Gaol, Dolphin’s Barn and the Crumlin Road around the halfway point.
Runners then head through areas including Cromwellsfort, Templeogue and Terenure before approaching one of the more notorious parts of the race.
And Then Comes “Heartbreak Hill”
A marathon rarely keeps its most difficult conversation until the beginning.
Dublin certainly doesn’t.
During the final 10km, runners face climbs along Milltown Road, Clonskeagh and Roebuck Road.
At approximately 35km comes the section known as Irish Heartbreak Hill — a particularly unwelcome incline when there are already more than 21 miles in the legs.
Fortunately, what goes up eventually comes down.
The route continues towards Stillorgan Road, Nutley Lane and Merrion Road, passing the RDS before runners finally reach the finish at Pepper Canister Church.
For spectators, the route also provides plenty of opportunities to experience different parts of Dublin while supporting runners.
Running Dublin Marathon? Don’t Forget the Expo
One practical detail is particularly important for anyone travelling to Dublin for the race.
Successful entrants must collect their race number and race pack in person at the Dublin Marathon Expo on the Friday or Saturday before race day. Organisers state that this is a mandatory part of the event’s safety and identity-verification process.
That makes arriving in Dublin ahead of Sunday morning especially important.
Rather than travelling into the city at the last possible moment, arriving earlier gives you time to collect your race number, organise your kit, eat properly and become familiar with your surroundings before race morning.
Not Running? Dublin Marathon Is Still Worth Experiencing
You don’t need a race number to enjoy Dublin Marathon weekend.
Some of the best memories belong to the people standing along the route.
The marathon moves through residential communities as well as Dublin’s famous landmarks, and support builds throughout the day as runners make their way around the city.
If you’re supporting a friend or family member, plan ahead rather than trying to follow them continuously.
Choose two or three places where you can realistically see them and allow plenty of time to travel between locations. Remember that road closures and race-day crowds will affect normal transport.
And when they reach you somewhere around 35km, enthusiasm is probably more valuable than telling them they “only have a few kilometres left”.
Why Stay at Clifden Guesthouse for Dublin Marathon Weekend?
For marathon weekend, location matters.
You don’t necessarily want to spend the morning of a marathon trying to navigate into Dublin from well outside the centre — and spectators benefit just as much from having the city within easy reach.
Clifden Guesthouse is located at 32 Gardiner Place in Dublin 1, within easy reach of O’Connell Street and central Dublin.
That gives runners and supporters a convenient base for exploring the city before and after the event.
You’re also staying somewhere with a little Dublin history of its own. Clifden is housed in a historic Georgian building, and no two rooms are exactly alike.
Room options include doubles/twins, triples and quad rooms, which can be particularly useful for couples, families or groups travelling to Dublin together for marathon weekend. Rooms include Wi-Fi and tea and coffee-making facilities.
Most importantly, staying centrally means Dublin is outside your door rather than at the end of another long journey.

What to Do in Dublin Before the Marathon
If you’re running, Saturday probably isn’t the day for an enthusiastic 25,000-step walking tour.
But there is still plenty you can enjoy without exhausting yourself.
A gentle walk towards O’Connell Street and the River Liffey gives you an opportunity to experience central Dublin without spending hours on your feet.
Have a relaxed meal, prepare everything you need for the morning and resist the temptation to test whether your marathon shoes “still feel okay” with an unnecessary 10km sightseeing run.
If you’re visiting as a supporter rather than running, you can explore considerably more.
From Clifden Guesthouse, central Dublin attractions including O’Connell Street are readily accessible, while the city offers Trinity College, Dublin Castle, the Guinness Storehouse, Phoenix Park and numerous museums and galleries.
After 26.2 Miles…
There is a very particular feeling that comes with finishing a marathon.
Relief. Exhaustion. Pride. Hunger.
Sometimes all four at once.
After collecting your medal and finding whoever has been supporting you, resist the urge to immediately plan an ambitious evening.
Walk gently. Eat. Rehydrate. Get warm.
Then, once you’ve recovered sufficiently, you’re in Dublin.
Whether celebration means a good meal, a quiet drink or simply getting back to your room and taking off your running shoes, staying centrally makes the post-race part of the weekend considerably easier.
The city will still be there in the morning.

More Than a Marathon
Forty-six years after those first runners took to Dublin’s streets, the marathon has grown beyond anything its original organisers could realistically have imagined.
There are faster courses. There are flatter courses. There are certainly courses without an Irish Heartbreak Hill waiting at 35km.
But Dublin’s attraction has never depended entirely on the course.
It’s the atmosphere of the neighbourhoods you pass through. The volunteer holding out a drink when you desperately need one. The family who have been waiting for hours to see their runner for ten seconds. The charity vest carrying somebody’s name. The stranger on the roadside telling you to keep going.
In 2026, another 22,500 runners will have their own reason for standing on Leeson Street.
Some will chase times.
Some will raise money.
Some simply want to prove that they can do it.
And 26.2 miles later, Dublin will be waiting for them at the finish.
