Welcome to Joe Duffy BMW Clontarf half marathon and 5 mile special Battle edition. This year is the commemoration of The Battle of Clontarf and we will make the 5th of July a day to remember. As you may have noticed we have a new Title sponsor with Joe Duff BMW. We also have a new sponsor in Erdinger Alcohol free. We look forward to working closely with them to make Clontarf the best race experience in 2014.

We have lots of new stuff for 2014 including a special collectors edition Battle medal. A pint of Erdinger Alcohol free at the finish line (over 18's only). And we will have Vikings - of course!  

The entry fee remains €30 making us one of the best value half marathons. The 5mile is €20 and Junior is €7. And most importantly we are Ireland's Flattest race(s). PB time.

Run, Jog or Walk (we have a dedicated walking section) but don't miss out on the race of 2014. Annual SELL OUT event. Places are limited. Enter now to avoid disappointment.

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