Your bib is color-coded by wave. You line up in your zone.
On the last Sunday of October 2022, Dublin surrenders its streets to 25,000 runners in one of Ireland's most storied athletic traditions — a marathon that has wound through the city's Georgian heart since 1980. From Fitzwilliam Street Upper to the finish at Merrion Square North, the 26.2-mile course becomes a temporary map of human endurance, threading past Trinity College, Phoenix Park, and the southern suburbs before the city reclaims itself by evening. The event is both a feat of individual will and a vast civic choreography, requiring staggered starts, extensive road closures, and the quiet cooperation of an entire city.
- 25,000 runners from Ireland and beyond converge on Dublin city centre on October 30th, creating one of the largest single-day disruptions to the capital's traffic and public life.
- Road closures begin as early as 3:30am and stretch until 9pm, rerouting traffic across dozens of streets and testing the patience of residents, commuters, and spectators alike.
- Organizers manage the surge of bodies through staggered wave starts — wheelchair users first, then four timed waves at five-minute intervals — to prevent dangerous congestion on the opening miles.
- Runners face a mixed forecast of sunny spells and heavy showers at 13–15°C, with officials strongly discouraging earphones so safety instructions from stewards can be heard above the noise of the course.
- Spectators can follow participants in real time via the Dublin Marathon Tracker, while Q-Park offers pre-booked discounts across the city to ease the logistical burden of the day.
On the morning of October 30th, Dublin hands its streets over to 25,000 runners for the 2022 Dublin Marathon — a race with roots stretching back to 1980, when 2,100 entrants produced 1,420 finishers and Dick Hooper claimed the first of his three victories. This year's field, drawn from Ireland and across the world, will gather at Fitzwilliam Street Upper from 8:30am, sorted into colour-coded waves that depart in five-minute intervals beginning at 8:40am. Wheelchair users lead the way, followed by four timed waves through to 9:45am — a careful sequencing designed to keep thousands of bodies from colliding on the same stretch of road at once.
The 26.2-mile course traces a generous arc through Dublin's character: south past St Stephen's Green and Trinity College, through Herbert Park and into Phoenix Park, then across the Liffey at Chapelizod Bridge and through the working-class suburbs of Ballyfermot and Kilmainham before the halfway mark near Crumlin Road. The second half carries runners through Drimnagh, Kimmage, Walkinstown, Templeogue, Terenure, and Rathgar, before the route climbs the UCD flyover and descends toward the finish at Merrion Square North — where the entire field must arrive by 5pm.
Finishers receive a medallion, t-shirt, and goody bag — none of which can be replaced if lost — and are asked to clear the finish zone promptly for those still on course. Race bibs, collected at the Royal Dublin Society on Friday or Saturday, must be worn on the front; failure to do so risks being stopped mid-race.
The city itself transforms well before the starting gun. Road closures begin at 3:30am and ripple outward through the day, diverting southern traffic via Mount Merrion Avenue and Rock Road, and northern traffic through Dorset Street and Gardiner Street. Public transport delays are expected, and all involved are advised to build in extra time. Met Éireann forecasts a cool, unsettled day — sunny spells broken by showers, temperatures between 13 and 15 degrees, and a moderate southwesterly wind. Organizers urge runners to leave their earphones at home, reminding them that even closed roads will carry course and emergency vehicles throughout the day.
On Sunday morning, October 30th, the streets of Dublin will belong to 25,000 runners, walkers, and joggers—some traveling from across the world, others from every corner of Ireland. They will gather at Fitzwilliam Street Upper in the city centre, where the 2022 Dublin Marathon begins at 8:40am, though not all at once. The organizers have divided participants into four staggered waves, each departing at five-minute intervals, with wheelchair users starting first at 8:40am, followed by the main waves at 8:45am, 9:05am, 9:25am, and finally 9:45am. Your assigned wave depends on your previous marathon time, or an estimated time if you're running your first. This careful choreography exists to prevent the chaos of thousands of bodies converging on the same stretch of road at the same moment.
The course itself is a 26.2-mile loop that reads like a guided tour of Dublin's geography and history. From the starting point, runners move toward St Stephen's Green, threading through the Georgian streets that define the city's character, past Trinity College and Herbert Park. The route then carries them into Phoenix Park, where they exit via the Chapelizod gate and cross the River Liffey at Chapelizod Bridge. From there, the path winds through Ballyfermot and back toward the city, passing Kilmainham Gaol before hitting South Circular Road. Around the halfway point, near Crumlin Road, runners have covered the distance and the mental battle begins in earnest. The second half takes them through Drimnagh, Kimmage, and into the southern suburbs—Walkinstown, Templeogue, Terenure, and Rathgar—before the route turns back toward the city centre, ascending the UCD flyover and descending Stillorgan Road and Nutley Lane to the finish at Merrion Square North. The entire event must conclude by 5pm.
For those crossing the finish line, there are immediate logistics to manage. Each finisher receives a commemorative medallion, a t-shirt, and a goody bag—items that, once lost or mislaid, cannot be replaced. Organizers ask that runners move quickly through the finish zone to avoid blocking those still arriving behind them. The race pack, which includes your official bib number, can be collected at the Royal Dublin Society from Friday afternoon through Saturday evening. Your bib is color-coded by time zone, and you must line up in your assigned zone no later than 8:30am on race day. Wearing your number on the front is not optional; failure to do so could mean being stopped on the course.
The city itself will be transformed by road closures beginning at 3:30am and lasting until 9pm. Traffic from the south, coming down Stillorgan Road and wanting to reach the city centre, will be diverted through Mount Merrion Avenue, Rock Road, and a series of secondary routes. Northern traffic from Finglas Road and Ballymun Road will be redirected via Whitworth Road, Dorset Street, and Gardiner Street. The closures are granular and extensive—Leeson Street Lower closes at 7:45am, while streets like Chesterfield Avenue and College Road remain closed until mid-afternoon as the race progresses through different sections. Public transport services may experience delays, and both spectators and participants are advised to allow extra travel time.
For those watching from the sidelines, the Dublin Marathon Tracker will go live on race day, allowing family and friends to follow their runners' progress in real time through a dedicated link. The weather forecast from Met Éireann suggests a mixed day: sunny spells interrupted by showers, some heavy in the west and southwest, with temperatures reaching only 13 to 15 degrees Celsius in moderate to fresh winds from the south and southwest. Participants considering earphones are strongly discouraged—the organizers warn that music might prevent you from hearing crucial instructions or safety warnings from stewards, and even closed roads will see course vehicles and emergency vehicles passing through.
For those seeking parking, Q-Park locations throughout Dublin city centre are offering a 25 percent discount to marathon participants and spectators from October 29th through the 31st, using the promo code 'ILDM25'—though this must be pre-booked and is not available on the day itself. The Dublin Marathon itself carries history. It began in 1980 with 1,420 finishers from an entry of 2,100. Dick Hooper won that first race in 2:16:14 and remains the only three-time champion. Since then, Irish runners have dominated the podium, with 12 Irish women and 11 Irish men claiming victories. As Sunday approaches, the city prepares for a day when its streets will pulse with the effort of thousands of people chasing a finish line.

The Hearth Conversation Another angle on the story
Why stagger the start times? Why not just let everyone go at once?
Because 25,000 people leaving from the same point at the same moment creates a bottleneck that slows everyone down and makes the early miles chaotic. The waves spread the load across the course so runners have room to move and stewards can manage the flow.
So if I'm a slower runner, I start later?
Exactly. Your wave is assigned based on your estimated finish time. Faster runners go first, slower runners follow. It's not about judgment—it's logistics. Everyone gets a fair race.
What happens if I lose my finisher's medal?
You can't get another one. They don't replace them. So once you cross that line and collect it, you hold onto it.
The weather sounds miserable.
It's Irish autumn. Cool, wet, windy. Thirteen to fifteen degrees. You'll be moving for hours, so you warm up, but the rain will be real. Especially if you're out there for four or five hours.
Can I listen to music while I run?
They strongly advise against it. You need to hear the stewards if something goes wrong, and there are still vehicles on the course even though it's closed. Your safety depends on being aware of what's happening around you.
How do I know where to stand on the starting line?
Your bib is color-coded by wave. You line up in your zone no later than 8:30am. Wear it on the front where everyone can see it, or you might get pulled off the course.
