Irelands Flattest Half Marathon & 5 Mile. Next race November 21st. Ideal Ápres Marathon race

  • Opening soon. This November race will sell out (again). Don't leave too late....


Welcome to Joe Duffy BMW Clontarf half marathon and 5 mile. Back with a bang after the success of November in 2014. We have gone with the same formula which attracted 3,000 walkers, joggers and runners to this flat course in November. It certainly had the big race atmosphere

Cooler conditions and the reward of that 'almost famous' home made soup at the finish line make this a race worth considering. Perfect timing for those who have completed the Dublin Marathon. The training is done - so it could be a half marathon PB opportunity...

The entry fee is reduced to €27 for the half and €18 for the 5 mile. We reduce the price in November by eliminating Training tops (due to popular demand - medals for ALL have been re-introduced. Visual of a NEW medal design will be available shortly)

Run, Jog or Walk (we have a dedicated walking section). Annual SELL OUT event and places are limited. Enter now to avoid disappointment.  

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