  • Pacers for November Half Marathon. Times: 1hr 30, 1hr 40, 1hr 45, 1hr 50  & 2hrs


Welcome to Joe Duffy BMW Clontarf half marathon and 5 mile ÁPRES MARATHON EDITION. Back with a bang after the success in 2013. We have gone with the same formula which attracted over 1,700 walkers, joggers and runners to this flat course in November. 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 €26 for the half and €17 for the 5 mile. We strip down the price in November by eliminating tops and medals. 

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!
