Welcome to Joe Duffy BMW Clontarf half marathon and 5 mile. It takes place in the scenic setting of Clontarf Promenade and Bull Island with views of Howth Head and Dublin bay. The race is contained within an off road promenade and Bull Island giving it unique and relaxing appeal.

Both races are open to runners/ joggers and walkers. The flat terrain makes it an ideal race to aim for a PB. The half marathon has pacers to help you achieve your Goal. The 5 mile is all on hard surfaced ground.

Back with a bang after the success of 2022. We have gone with the same formula which attracted 3,600 walkers, joggers and runners to this flat course in November last year. It certainly has the big race atmosphere! Medals and goodies await you at our unique finish line.

This is an annual SELL OUT race. Don’t leave it too late to enter
