106th Dublin City Liffey Swim Opens Inaugural Liffey Festival as 320 Swimmers Take on 2.2km River Course
The 106th Dublin City Liffey Swim took place on Saturday, September 12, 2026, serving as the sporting centrepiece of the inaugural Dublin City Council Liffey Festival and drawing over 320 swimmers to the 2.2km open-water course that winds through the heart of the capital from Rory O'More Bridge near the Guinness Brewery to North Wall Quay in front of the Custom House — one of the most distinctive and beloved fixtures on the Irish sporting calendar, now entering its second century of competition.
Background
The Dublin City Liffey Swim has been held annually since 1920, making it one of the oldest open-water swimming events in the world and a unique piece of Dublin's sporting heritage. The race covers 2.2 kilometres through the centre of the city, passing under eleven bridges including the Ha'penny Bridge, O'Connell Bridge, and the Samuel Beckett Bridge — a course that takes swimmers through the living heart of the capital and provides spectators along the quays with a grandstand view of the competition.
The event has evolved significantly over its 106-year history. What began as a relatively informal competition has grown into a well-organised event that attracts swimmers of all ages and abilities, from elite open-water specialists to recreational swimmers completing the course for the first time. The tidal nature of the Liffey means that the race conditions vary significantly depending on the time of the tide, with the women's race traditionally held against the incoming tide and the men's race beginning shortly after high tide.
The 2026 edition carries additional significance as the centrepiece of the inaugural Dublin City Council Liffey Festival, a two-day celebration of the river through cultural, maritime, and sporting activities. The festival represents a broader effort by Dublin City Council to reconnect the city with its river, which has historically been treated as a boundary to be crossed rather than a resource to be celebrated.
Key Developments
The 2026 Liffey Swim attracted over 320 competitors, with the women's race commencing at 12:00 PM and the open/male race beginning at 1:30 PM. The event was officially started by Lord Mayor of Dublin, Councillor Daryl Barron, in a ceremony that reflected the civic importance of the occasion. Water temperatures in the Liffey in September typically range between 13 and 15 degrees Celsius — cold enough to require acclimatisation but manageable for experienced open-water swimmers.
The field included a remarkable range of ages and experience levels. Among the youngest competitors were 13-year-olds Maria O'Dwyer, Lex Healy, and Bruce Healy, while the oldest male competitor was 76-year-old Tony Byrne. Derek "Bimbo" Wilkes, a veteran of the event, competed in his 56th Liffey Swim — a record of participation that speaks to the event's capacity to inspire lifelong commitment to open-water swimming. The 2025 women's winner, Liz Keary, was among the returning competitors seeking to defend her title.
The Liffey Festival programme surrounding the swim included maritime activities, cultural events, and community celebrations along the quays, with the river itself serving as the focal point for a day of public engagement that drew thousands of spectators to the waterfront.
Why It Matters
The Liffey Swim matters because it is one of those rare sporting events that belongs to the city rather than to any particular club or organisation. The sight of hundreds of swimmers making their way through the centre of Dublin, past the landmarks that define the capital's identity, is a reminder that sport can be a form of civic celebration as well as competition. The event's longevity — 106 years of continuous competition, interrupted only by the most extreme circumstances — is a testament to the enduring appeal of the challenge it presents and the community that has grown up around it.
The inaugural Liffey Festival adds a new dimension to the event, situating the swim within a broader celebration of the river that has the potential to become an annual fixture in Dublin's cultural calendar. The festival reflects a growing recognition that the Liffey — long associated in the public imagination with pollution and neglect — has been transformed in recent decades into a genuine urban amenity, with improved water quality, new riverside developments, and a growing culture of river-based recreation.
Local Impact
The Liffey Swim draws spectators to the quays from across Dublin and beyond, with the bridges along the course providing natural viewing platforms for thousands of onlookers. Businesses along the quays — cafés, pubs, and restaurants — benefit from the increased footfall, and the event provides a boost to the local economy at a time of year when the summer tourist season is winding down. For the swimming community, the Liffey Swim is a highlight of the open-water calendar, attracting competitors from clubs across Leinster and beyond. Swim Ireland, the national governing body, has been supportive of the event's development and sees it as an important showcase for open-water swimming in Ireland.
What's Next
The results of the 2026 Liffey Swim will be published by Swim Ireland in the days following the event. The Liffey Festival programme continues through Sunday, with further cultural and maritime events along the quays. Planning for the 107th Liffey Swim will begin in the coming months, with the event expected to return in September 2027 as part of what organisers hope will become an established annual festival format.
