Dublin Marathon

The Race

History

Dublin's first marathon happened almost by accident of persuasion. In 1980, the Irish athlete and broadcaster Noel Carroll talked the Business Houses Athletic Association into backing a mass-participation city race, at a time when New York and London had already shown what a marathon through a capital could become. Some 2,100 runners lined up that October. Only 1,420 finished. Dick Hooper won the men's race in 2:16:14; Carey May took the women's title in 2:42:11, leading home a field of just forty women, a reminder of how recent it still is that female marathon participation was treated as a footnote rather than half the entry list.

The race grew into Ireland's biggest running event and settled into the autumn calendar as a fixture of the October bank holiday weekend, before the organisers shifted it to the Sunday in 2016, aligning Dublin's logistics with the international norm and easing travel for runners flying in from Britain and further afield.

What has stayed constant is the character of the thing. Dublin has never tried to be Berlin. There is no flat, laser-straight boulevard chasing a world record, no PB-factory reputation to defend. Instead the race threads Georgian squares, Phoenix Park and unglamorous southside suburbs, and it leans on its own claim to fame: crowd warmth. Runners consistently describe neighbourhoods that turn out in force, brass bands, and a level of good-natured heckling that would not be out of place in a Roddy Doyle novel. The race has become the host event for the Athletics Ireland National Marathon Championships, giving it a domestic sporting weight beyond its status as an international city marathon. In 2024, Moses Kemei of Kenya won in 2:08:47, and Ethiopia's Asimarech Naga ran a women's course record of 2:24:13. Behind them, Hiko Tonosa's 2:09:42 was reported by RTÉ as an Irish record, finishing third overall: a result that did more for Dublin's elite credibility in one afternoon than a decade of marketing.

For 2026, the organisers moved general entry to a ballot, explaining that around 70 per cent of places in recent years had gone to returning runners. It is a deliberate reset, designed to widen access and lift female participation, and it changes how international runners should plan: Dublin is no longer a race you can simply decide to enter in September.

The course

The course starts on Leeson Street Lower in Georgian Dublin and finishes on Mount Street Upper, close to Pepper Canister Church. It opens downhill past St Stephen's Green, climbs briefly on Patrick Street toward Christ Church Cathedral, then drops to the Liffey and crosses to the Northside. Phoenix Park absorbs the 6–16 km stretch, taking in Dublin Zoo, Chesterfield Avenue and the course's highest point, around 70 m above sea level near the 11 km mark. From Castleknock the route drops through Chapelizod, Inchicore and Kilmainham before an undulating middle third through Dolphin's Barn, Crumlin, Templeogue and Terenure. The defining test comes late: a drag through Dartry, Milltown, Clonskeagh and Roebuck Road, known locally as Irish Heartbreak Hill, arrives around the 33–36 km mark. The final six kilometres descend via Fosters Avenue and Stillorgan Road, pass RTÉ at Nutley Lane, and run in along Merrion Road to the finish near Pepper Canister Church. The surface is road throughout. No official kilometre-by-kilometre elevation table has been published by the organiser.

Km 0–6: Georgian Dublin and the first sting.The start on Leeson Street Lower drops away almost immediately, past St Stephen's Green and into the Liberties. It is a deceptive opening: gravity and crowd noise conspire to make three-hour pace feel easy, and that is precisely the trap. Patrick Street brings the first real work of the day, a short climb toward Christ Church Cathedral, before the route tips back down to the Liffey and crosses to the Northside near Aughrim Street, where the first water station appears. Nothing here decides the race. Running it too well can.

Km 6–11: Into Phoenix Park.The route enters Phoenix Park just after 6 km, past Dublin Zoo and along Chesterfield Avenue, and does not let go until Castleknock. This is the longest continuous climb of the day, gaining roughly 50 m over five kilometres to the course's high point of around 70 m near the 11 km mark. It is not steep by any objective measure, but it is sustained, and the openness of the park means wind, when there is any, gets a clear run at you. Support thins out here simply because there is more park than pavement.

Km 11–16: The long give-back. What Phoenix Park takes, it returns. After a short climb out near Castleknock and a re-entry at Knockmaroon Gate, the course drops steadily through Chapelizod, Inchicore and past Kilmainham Gaol, losing more than 60 m by the 16 km mark, the lowest point on the course since the opening kilometres. It is tempting to let this section run away with you. Resist banking time here as firmly as you resisted it on the opening downhill.

Km 16–24: The undulating middle.Through Dolphin's Barn and Crumlin Road the terrain turns gently lumpy rather than dramatic, and the third block of the race, via Cromwellsfort, Fortfield Road, Templeogue and Terenure, offers flatter, faster stretches between the rises. This is Dublin's most ordinary running, in the best sense: neighbourhood streets, local crowds, a race settling into its rhythm before the work resumes.

Km 24–30: Dartry and the false summit. A second, smaller climb builds through this stretch, peaking twice around 24 km and again near 27–28 km at close to 50 m. It is not the named hill Dublin is famous for, but it arrives at a point in the race where legs are already tiring, and runners who treated the Phoenix Park climb carelessly often feel this one more than the mileage alone would suggest.

Km 30–36: Irish Heartbreak Hill.The course's defining test. After Dartry Road, the drag through Milltown, Clonskeagh and up to the top of Roebuck Road is famous locally as Irish Heartbreak Hill, cresting around the 35 km mark. It is late rather than brutal: a long, grinding rise of perhaps 20 m that would be unremarkable at 10 km and feels considerable at 35. The best response is not heroics. Shorten the stride, hold cadence, and accept that effort will spike for a few minutes without panicking about pace.

Km 36–42.195: The run for home. The descent along Fosters Avenue and across the Stillorgan Road flyover gives the legs something back, though the turns near RTÉ and Nutley Lane mean this is not a simple freewheel to the line. Merrion Road and the approach past the RDS bring the race back into denser, louder support, and the finish near Pepper Canister Church has a distinctly Dublin character rather than the anonymous corporate gantry of some bigger races.

The course is marked in miles and every 5 km, with timing mats at the start, 10 km, halfway, 30 km, 40 km and the finish. Runners who train in kilometres should be ready to recalibrate their mental markers on the day. No blue tangent line has been confirmed on the current course; treat kerb-hugging as a matter of local road knowledge rather than a marked guide.

Elevation profile

Elevation figures are GPX-derived (from the plotaroute.com file linked on the official course page), not from an official measurement certificate.

Pacers

Pacers aim to finish a few seconds under their target time and are identified by large balloons; earlier editions used backpacks, so check the latest final instructions before race week.

What to wear

Late October in Dublin sits at the damp, breezy end of temperate, and race-day temperatures typically run 10–14°C at the start, according to Met Éireann's general climate data for the period. That is close to ideal for marathon running once moving, but it can feel raw for the thirty or forty minutes spent standing in a start pen on Leeson Street Lower. A throwaway top, old gloves and a bin-bag poncho are the standard kit for the wait; none of it needs to survive past the start gun. Rain is a real possibility rather than a remote one: Ireland's Atlantic weather systems bring frontal rain and showers through October and November, so a cheap, breathable throwaway layer earns its keep more reliably here than in a drier European autumn city.

Once running, most people are comfortable in a singlet or light long sleeve with shorts; overheating is a smaller risk than in warmer marathon cities, and the later, hillier stretches of the course generate their own heat regardless of the air temperature. Sunscreen is a lower priority than in spring or summer races, though late-wave runners finishing in early afternoon sun after a clear morning should not assume it is unnecessary. Wind exposure is most noticeable in the open stretches of Phoenix Park between 6 and 11 km; a light windproof layer, if not needed for warmth, is still worth carrying for that section on blustery years.

Entry

For 2026, Dublin replaced its previous priority-entry system with a general ballot, a change the organisers linked directly to the fact that roughly 70 per cent of recent places had gone to returning runners. The ballot opened for six days from 07:00 on Wednesday 12 November 2025 and closed at midnight on Monday 17 November 2025, with results issued in two batches on 25 and 26 November. The organiser has said 2027 details will follow later in the year, so the safest working assumption for prospective entrants is a similar November ballot window before the 2027 race.

The 2026 entry fee was €110 plus a €5.50 handling charge, roughly £99 at the euro exchange rate on 1 July 2026 (EUR 1 = GBP 0.85973), before any card or provider fees. General ballot and charity entries carry no qualifying-time requirement. Good For Age is the separate fast-runner route: for 2026 it opened 1 May and closed 19 May, open to anyone who had achieved a qualifying time within the previous two years, with a one-entry-per-person cap, notification of successful applicants, and 72 hours to accept an offered place. Applying does not guarantee a place. Good For Age standards were published only as an image on the official page during research and could not be extracted as text; check irishlifedublinmarathon.ie/good-for-age-standards/ directly for the current age-and-gender qualifying times before relying on a specific figure.

Charity entry runs through realbuzz and more than 150 partner charities from Ireland and abroad, a route worth considering for anyone missing the ballot and comfortable with a fundraising commitment that varies charity to charity. International tour operators are also officially recognised, including Sports Tours International (UK), Marathon Tours and others; packages can bundle a guaranteed place with accommodation, though some are restricted by residency.

The 2026 refund window ran 1–12 July 2026, and the transfer window 22 July–23 September 2026, managed through Eventmaster with a €20 fee charged to the person receiving the place. Transfers outside the official window are strictly prohibited. For anyone planning 2027, the sensible sequence is: watch for the autumn 2026 ballot announcement, hold a flexible, cancellable hotel booking before results, and avoid non-refundable travel until a place is confirmed, unless travelling through an official tour operator.

Race Weekend

Expo and Bib Collection

The Expo and race number collection run from the Main Hall at the RDS (Royal Dublin Society), Simmonscourt Road, Ballsbridge, Dublin 4. For 2026, opening hours were Friday 23 October, 12:00–19:00, and Saturday 24 October, 09:00–18:00, with 18:00 on the Saturday as the hard cut-off for collection. Runners must collect their own number and pack in person; no proxy-collection policy was confirmed in the pages accessed during this research, so treat collection as strictly in-person unless the final instructions for the year say otherwise. Bring photo ID and registration confirmation.

The RDS sits south-east of the city centre in Ballsbridge, a short walk or bus ride from several marathon-weekend hotel clusters. Dublin Bus routes 4, 7, 7A and S2 stop at the Merrion Road entrance; route 18 also serves the RDS directly, and routes 46A, 145, 7B, 7D, 39A, 84X, 116 and 155 stop within roughly ten minutes' walk along Stillorgan Road or Donnybrook Road. On-site parking is limited and charged.

The practical advice is straightforward: treat the Expo as a Friday or Saturday job, not a race-morning one. Runners based in Ballsbridge can walk to collection and are well placed for the closing stages of the course, while those staying around St Stephen's Green or Merrion Square will need a short bus ride or a twenty-to-thirty-minute walk each way. Saturday afternoon tends to be busier than Friday, so an early Saturday visit, or Friday itself if travel plans allow, avoids the worst of the queue.

Getting to the Start

Wave start times: Wheelchair 08:40, Wave 1 08:45, Wave 2 09:05, Wave 3 09:25, Wave 4 09:45.

The start sits on Leeson Street Lower, in Georgian Dublin, with entry zones colour-coded by bib and wave; check the final instructions each year for exact road closures and entry points, since these shift slightly from edition to edition. The 2024 final instructions advised arrival no later than 08:00, and that guidance is a reasonable planning baseline for 2027 pending confirmation.

Runners staying around Merrion Square, St Stephen's Green or the wider Georgian Quarter can walk to the start directly, already dressed to run, carrying only the official clear plastic baggage bag if using bag drop. This is the least stressful option and the one worth prioritising when booking accommodation. From Temple Bar or Trinity, the walk to Leeson Street is roughly 15–25 minutes depending on the exact hotel, and walking is more reliable than buses on the morning itself, since closures affect normal routes. From Ballsbridge, the walk is longer but manageable for most runners, particularly those who value proximity to the RDS for Expo convenience over a shorter race-morning walk. No official source confirms free public transport for entrants on race day, so a Leap card, contactless payment, or a walkable hotel should be the working assumption.

Start-zone facilities include toilets by wave and a baggage area accepting only the official clear plastic bag: rucksacks and holdalls are turned away. Hydration vests are permitted but may be searched at zone entry. There are no changing facilities at the start, so arrive dressed to run under a throwaway layer.

Non-competitors may not enter the course or cross the finish line with a runner; the final instructions specifically warn against carrying children to the finish. Cycling alongside runners is forbidden and can result in disqualification. Headphones are not formally banned but are discouraged, since runners need to hear stewards and emergency vehicles; noise-cancelling models in particular are worth leaving at the hotel.

Nutrition on Course

The most recently accessible detailed schedule comes from the 2024 final instructions, cross-checked against current FAQ wording confirming the same brands: Ishka water, Lucozade Sport and High5 gels.

Ten water stations in total on the 2024 course, with Lucozade Sport at four of them and High5 gels at two, around 16 and 22 miles. Cups are used at several stations rather than bottles throughout, so practising a drink-on-the-move technique in training is worth the effort. Personal bottle service was not confirmed as available in the pages accessed during this session. Given only two gel stations on the official course, most runners carrying their own nutrition plan should bring the bulk of it themselves rather than relying on aid-station gels, particularly for anything beyond about three hours of running.

Spectating

Dublin rewards spectators who plan around the road closures rather than fighting them. Two or three sightings plus the finish is realistic for most people on foot with occasional public transport where services are confirmed running; a fourth is possible for locals who know the closure pattern well, but for visitors it tends to turn support into a transport exercise rather than a day out.

The single best fixed spot is around Merrion Road and the RDS on the final approach: it is late enough in the race to matter emotionally, close to the Expo and accommodation zone, and positioned to let spectators move on to the finish meeting area afterwards without much of a walk. For early energy, St Stephen's Green and the Liberties are lively, but the field passes quickly and the crowds there are dense and hard to move through.

Crowd density is strongest at the start and finish zones, the Phoenix Park gateways, Castleknock, and the neighbourhood stretches through Terenure and Milltown. It thins out inside the park itself and on some of the connector roads in the mid-race suburbs, where the field naturally spreads. The finish area operates a restricted, congested one-way system rather than a casual meeting point, and runners cannot be met on the course itself. The organiser's app carries live tracking, usually shared closer to race week.

Route A (sub-3:30):Start near St Stephen's Green / Leeson Street for the opening kilometres (Wave 1 start 08:45), walk or take a confirmed bus route toward Phoenix Park / Castleknock for the 8–11 km stretch if timings allow, then return to Merrion Road / RDS for the final approach, roughly 30–36 km depending on pace.

Route B (around 4:00–4:30):Start near St Stephen's Green for the opening kilometres, reposition to Terenure or Dartry for the 24–28 km stretch, allowing generous transfer time given road closures, then finish at Merrion Road / RDS for the final kilometres and post-race meeting point.

Route C (single location): Stay at Merrion Road / RDS throughout, watching the field pass on the outbound stretch near the start if the route permits, then again on the final approach. Suits spectators unwilling to navigate closures, or those supporting several runners across a wide range of finish times.

Exact bus/Luas/DART line names for these itineraries were not confirmed as running on unaffected routes during marathon closures. Cross-check against Transport for Ireland's race-day notice before relying on specific line numbers.

The Finish

Finishers pass through a one-way system and cannot be met by family at the finish line itself; the designated post-race meeting areas near Merrion Square are the place to reunite. Every finisher receives a medal, T-shirt and goody bag, none of which can be replaced if lost, so keep hold of the bag once collected. For hotels around Merrion Square, St Stephen's Green, Trinity or Ballsbridge, walking back is usually the least stressful option once legs allow; for anywhere further out, check TFI's live journey planner once road closures begin reopening through the afternoon.

No changing rooms or showers were confirmed at the finish area. On-course or finish-line massage was not confirmed in the accessible official pages. No pregnancy or medical deferral policy was located during this research session.

Where to Stay

The finish sits in Georgian Dublin, near Mount Street Upper and Pepper Canister Church, so the strongest race-weekend bases are the neighbourhoods immediately around it rather than anywhere further afield.

Merrion Square and the Georgian Quarter

The best all-round base if the budget stretches to it. It sits closest to the finish, is comfortably walkable to the start, and trades the noise of Temple Bar for elegant streets and museums. Expect high marathon-weekend rates and limited late availability; this is not the neighbourhood for anyone booking in the week before the race.

St Stephen's Green

St Stephen's Green runs it close, particularly for the start. It has central hotels, restaurants and easy access to Grafton Street, and suits first-time visitors who want a genuinely central weekend. Saturday-night noise varies street by street, so a hotel on a quieter side road is worth the extra care in booking.

Temple Bar and Trinity

Temple Bar and Trinity offer maximum tourist convenience, walkable to both start and finish, with the Book of Kells and the Liffey on the doorstep. Temple Bar itself can be loud on a Saturday night before an early Sunday wave start, so runners who need sleep should pick a Trinity-side hotel rather than one in the thick of the pub strip.

Ballsbridge

The practical choice for anyone prioritising the Expo: it sits right by the RDS, has larger hotels with a calmer, more residential feel, and still works for the start on foot or with a short pre-planned journey outside the closure zone. It is not as convenient for race morning as Georgian Dublin, but the trade-off suits runners who would rather have an easy Saturday than an easy Sunday.

Portobello and Rathmines

Portobello and Rathmines, south of the centre, offer better value and more neighbourhood character than the absolute core, at the cost of a longer walk or a short taxi once closures are in effect. They suit repeat visitors and anyone travelling on a tighter budget who does not need the shortest possible post-finish walk.

Docklands

Docklands rounds out the options: modern hotels, good airport coach links, and proximity to EPIC and the river, though it is the least convenient of the group for both start and finish, and race-day DART changes need checking in advance.

Book as close to Merrion Square as the budget allows regardless of neighbourhood: the walk home on tired legs matters more than the walk out on fresh ones.

Booking Timeline

Dublin's booking calendar is shaped by the ballot rather than the race date. Results for the 2026 edition were released in two batches on 25 and 26 November, roughly eleven months before race day, which gives entrants an unusually long runway compared with races that confirm places closer to the event. The safest approach is to hold a flexible, free-cancellation booking in a preferred neighbourhood as soon as the ballot opens, rather than waiting for results, since the best-located hotels around Merrion Square and St Stephen's Green sell out or raise rates well before the race itself. Marathon-weekend pricing in central Dublin climbs noticeably in the final six to eight weeks before the race, particularly for anyone booking after results are announced with no existing reservation to fall back on. Flights from the UK and near Europe are short-haul and frequent, so flight booking is less time-critical than accommodation, though prices firm up as October approaches. Runners entering through an official tour operator can sidestep this timeline entirely, since accommodation is typically bundled with a guaranteed place.

Recommended hotels

See & Do

Trinity College and the Book of Kells

1.2 km (0.7 miles) from finish. The obvious "read before you run" stop in Dublin, and close enough to the finish-area hotels to manage on sore legs. Book a timed slot in advance; queues on a normal Saturday are long before you add marathon weekend to the mix.

St Stephen's Green

1 km (0.6 miles) from finish. Free, central and genuinely useful as a gentle shakeout walk rather than a tourist obligation. It also sits on the opening stretch of the course, so runners can retrace the first kilometre without the crowds.

Guinness Storehouse

3.5 km (2.2 miles) from finish. Dublin's biggest indoor draw, with tickets from around €22 and a visit of roughly ninety minutes to two hours. Better suited to a taxi or Luas trip than a walk on the day after the race.

EPIC The Irish Emigration Museum

1.8 km (1.1 miles) from finish. An indoor, low-walking alternative in the Docklands, with self-guided visits averaging around seventy minutes. A strong wet-weather choice for a tired Monday.

Phoenix Park

5 km (3.1 miles) from finish. A chance to see the course's signature climb without the race pressure attached to it. Open around the clock, though the scale of the park is easy to underestimate on legs that ran through it twelve hours earlier; a taxi there and a short loop is more sensible than a full circuit.

After the Race

Dublin's DART coastal railway is one of the most useful post-race recovery tools in European marathon running. The coast north and south of the city is accessible in 25 to 35 minutes, flat throughout, and at its autumn best in late October.
