Clontarf Half Marathon and 5 mile – November

Welcome to the Joe Duffy BMW Clontarf Half Marathon and 5 Mile, where you’ll experience the beauty of Dublin’s coastline like never before. This year’s race takes place along the stunning Clontarf Promenade and Bull Island, offering runners breathtaking views of Howth Head and Dublin Bay.

Whether you’re a runner, jogger, or walker, both races are open to everyone looking to challenge themselves and achieve their goals. The flat terrain of the race course makes it an ideal choice for runners aiming for a personal best, and the half marathon even has pacers to help you stay on track.

The 5 mile race takes place entirely on hard-surfaced ground, ensuring a smooth and comfortable run for all participants. And with our unique finish line, you’ll be greeted with medals and goodies to celebrate your accomplishment.

Back with a bang after the success of 2022, we’re using the same formula that attracted 3,600 participants to this flat course last November. The race has a big-race atmosphere, and it’s no wonder that it’s an annual sell-out event. So don’t wait too long to register and secure your spot at the starting line.

So what are you waiting for? Sign up now for the Joe Duffy BMW Clontarf Half Marathon and 5 Mile on November 18th and experience the beauty and excitement of this unforgettable race.

Please make every effort to place water bottles and caps in the bins provided at water stations and at the finish area.  PLEASE do not drop bottles/caps along the route.  We are lucky to be running in such a scenic location and littering the route jeopardises future events!
