That's all from us. Well done to all the runners today. The Kenyans once again showed their dominance in the sport, capturing both the men's and women's titles. There are still plenty of athletes out there pushing themselves towards the finish line so give them a cheer if you're around.
Next stop is New York, which hosts its marathon next weekend, although they have a hurricane to contend with in the meantime.
Back here, expect the whole thing to have wrapped up by about 5pm and stay tuned for traffic updates.

Some vehicular problems on the N4 this morning caused this reporter to be a bit slow off the mark for the IT live blog coverage of the 2013 Dublin Marathon. Still, as many of the athletes competing in today's race will appreciate, better late than never.
