Clontarf Half Marathon
Please check with Race Organiser for updates.
The Joe Duffy Group Clontarf Half Marathon returns to the beauty of Dublin's coastline on 4 July 2026.
Set against the stunning backdrop of the Clontarf Promenade and Bull Island, this race offers runners breathtaking views of Howth Head and Dublin Bay.
The Half Marathon course journeys up along the Dublin Coast, along Clontarf Road on the promenade and then on the inbound lane of the Howth Road. The route travels past St. Annes Park and on to Sutton, before turning around and working their way back over to Bull Island & down the coast.
The Clontarf Half Marathon is held twice annually in July and November.
