Welcome to Joe Duffy BMW Clontarf half marathon and 5 mile. This is Ireland’s flattest half marathon and flattest 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 Sell Out success of Nov 2022. We have gone with the same formula which attracted 3,200 walkers, joggers and runners to this flat course in July. 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.

Run, Jog or Walk (we have a dedicated walking section) but don’t miss out on the Ápres Marathon race of 2022. Annual SELL OUT event. Places are limited. Enter now to avoid disappointment.

Go out, be active, and most of all enjoy!
