Dublin Marathon

The bank-holiday marathon: out through Phoenix Park, round the southern suburbs, and home past the Georgian squares.

Overview

On the Sunday of the October bank-holiday weekend, 22,500 runners go round Dublin on roads closed since three in the morning. Every edition since 2019 has sold out.

The course is a loop that starts and finishes in the Georgian south of the city, 780 m apart. It drops to the Liffey quays, climbs through Stoneybatter into Phoenix Park, and comes back through Chapelizod, Crumlin and Terenure. Then comes the one stretch everyone warns you about: Clonskeagh and Roebuck Road at 34 km.

It isn't a flat course. It climbs 232 m, about three times Berlin, and its vertical range of 68 m is within a metre of New York's. But it ends kindly. After Roebuck the course runs downhill for three kilometres, to 2 m on Merrion Road, and the last three rise only 8 m to the line.

Reading the profile

Most of the climbing, 141 m of it, comes in the first half. The road rises from 2 m on the quays at 2.7 km to the high point of the course, 70 m near the Castleknock Gate of Phoenix Park at 11.5 km. The steepest climbing kilometre is the first real one: 18 m up from the river through Stoneybatter, from 3.6 km.

What the park gives, it takes back quickly. The steepest kilometre of the race is a descent, 25 m lost from 14.3 km, out of the park and down to the Liffey at Chapelizod. Then the course climbs again, more gently, to about 52 m through Kimmage and Terenure between 24.0 km and 28.0 km.

Roebuck hurts because of where it comes. From 17 m at 33.5 km the road rises to 44 m at 35.9 km. On the way, the steepest climbing kilometre of the second half gains 15 m. After that the course falls to its lowest point, 2 m on Merrion Road at 39.1 km. It finishes 10 m above sea level, 4 m lower than it started. Add up the energy cost of every gradient and, for a three-hour runner, the course comes out about 30 seconds slower than a flat 42.195 km (0.25 %).

How to enter: ballot odds

From 2026 every general place goes through one ballot. It opened on 12 November 2025 and closed five days later. About 47,000 people applied for roughly 17,200 ballot places, a little better than one in three. It replaced a priority window that had handed about 70 % of places to people who ran the year before; the organiser changed it to bring in more first-timers and more women.

Applying costs €5, which comes off the entry fee if you're drawn and is kept if you aren't. The fee itself is €110, plus a €5.50 handling charge.

Around the ballot there are Good for Age times, charity places (more than 150 charities hold them), and places set aside for elite and community programmes. Transfers for 2026 closed on 23 September. The organiser says details of the 2027 ballot will come later in the year.

History

In 1980 Noel Carroll talked the Business Houses Athletic Association into staging a city marathon in Dublin on the New York model. It ran on the October bank-holiday Monday. Of the 2,100 who entered, 1,420 finished, and Dick Hooper won in 2:16:14. Two years later the running boom brought 11,076 entries, a number the race would take decades to see again.

It stayed on the Monday for thirty-six years. In 2016 it moved to the Sunday of the same weekend, so that runners from abroad could make a long weekend of it, and entries rose by about 30 % in the first year.

The layout changed in 2024. The start moved to Leeson Street Lower and the finish to Mount Street Upper, by the Pepper Canister Church, a few hundred metres from each other in the Georgian south of the city. The course between them is the one Dubliners know: the quays, Phoenix Park, the southern suburbs, and Roebuck Road at 34 km.

The clocks go back at 2:00am on race morning. Irish summer time ends that night, so every start time here is GMT and you get an extra hour of sleep, or an hour of confusion if your phone and your hotel disagree. Road closures run from 3:00am to 9:00pm.

Start and finish are a short walk apart in the Georgian south of the city. You start on Leeson Street Lower by St Stephen's Green and finish on Mount Street Upper beside the Pepper Canister Church. Bags go to Merrion Square North, in the clear official bag only, into one of four areas by wave colour. Orange opens from 7:15am and green from 7:35; blue follows from 7:55 and purple from 8:05.

Drinks stations sit roughly every two to three miles, from Aughrim Street near mile 3 to Nutley Lane near mile 24. Pacers run every ten minutes from 3:00 to 5:00 across the four waves. At about 40 km the course passes the RDS in Ballsbridge, where numbers are collected.

Frequently asked questions

Is the Dublin Marathon hilly?

It climbs 232 m, about three times as much as Berlin. Its vertical range, 68 m from 2 m to 70 m, is within a metre of New York's. Most of the climbing is in the first half, which gains 141 m, and the second half is kinder. It won't flatter your time.

Sonny's LiDAR DTM of Europe, sampled every 25 m, smoothed over 100 m. Raw-to-smoothed ratio 1.45.

Where is Heartbreak Hill in Dublin?

Clonskeagh and Roebuck Road, between about 33.5 km and 36.0 km. The road rises from 17 m to 44 m in that stretch, and its steepest kilometre gains 15 m. Phoenix Park is the bigger climb, but this one arrives when your legs are empty. After it the course runs downhill to Merrion Road.

This site's course line; the organiser calls it the Irish Heartbreak Hill, at about 35 km.

Why do the clocks matter on race day?

Irish summer time ends at 2:00am on race morning. The race starts at 8:45am GMT, which is an hour later by your body clock than the same time the day before. The same was true in 2024 and 2025. Set a manual alarm, and don't trust every device to have caught up.

The organiser's FAQ gives timing in GMT; the clock change is the last Sunday in October.

Is the Dublin ballot the only way in?

For most runners, yes: from 2026 it takes every general entry. The 2026 ballot opened on 12 November 2025 and ran for five days. About 47,000 applied for roughly 17,200 places. The other routes are a Good for Age time, a charity place and the reserved elite and community places. The 2027 ballot hasn't been announced.

Reported ballot figures, June 2026; the organiser's registration page.

Is it a good first marathon?

It's a popular one, and the organiser moved to a single ballot partly to bring in more first-timers. The course is harder than its friendly reputation suggests: the climb into Phoenix Park comes early and Roebuck Road late. There are no intermediate cut-offs, and the course stays open until seven hours after the last runner starts.

Organiser FAQ for the time limit; this site's course line for the climbs.

Is a Dublin time eligible for records?

Yes. The course loses 4 m net against a World Athletics limit of about 42 m, and its start and finish are 780 m apart against a limit of half the race distance. It clears both comfortably. Kemal Husen set the course record of 2:06:52 here in 2023.

Measured from Leeson Street to Mount Street on this site's line; the rule is World Athletics Competition Rule 31.21.

Where do start and finish sit?

Close together, which makes the day simple. The start is on Leeson Street Lower by St Stephen's Green, the finish on Mount Street Upper by the Pepper Canister Church, and baggage is on Merrion Square North between them. All three are inside a ten-minute walk.

The organiser's 2026 start and finish map.

How many people run it?

The 2025 race sold out at 22,500 entries. In 2024, 18,091 of the entrants started and 17,719 finished.

Organiser figures for the 2025 edition.

What is the weather like on race day?

About 9.9 °C during a typical race: that's the median across 29 years, which have run from 7 °C to 14.3 °C. 3 of the 29 were wet.

ERA5 reanalysis for the race date, 1995-2025.

Can I use a time here to qualify for Boston?

The course is certified, and its net change is a drop of under 4 m, far short of the 1,500 ft where the B.A.A.'s downhill adjustment begins. So yes. The climbing is the harder part. Dublin gains 232 m, and Roebuck Road arrives at 34 km, when a qualifying pace is hardest to hold.

Net drop −4 m from this site's course line; 2027 adjustment None. Certification elite label: World Athletics Elite Label, confirmed on the label list for 2024.

How accurate is the elevation figure?

It comes from Sonny 1" .hgt tiles — CC BY 4.0, sampled every 25 m along the course line and smoothed over 100 m. The raw-to-smoothed ratio here is 1.45. Around 1.3 means the model is reading the ground, not rooftops; above about 2.0 the total climb carries real noise, and the net change is the sturdier number.
