One of the biggest endurance events of 2017 takes place on Sunday 20th August, as people flock to the capital to take part in Ironman 70.3.
The event is not for the faint-hearted; it involves a 1.2 mile swim, 56 mile cycle and 13.1 mile run. Taking in south Dublin, the city centre and the Phoenix Park, participants will also travel through parts of counties Meath and Kildare.
The swim will take place early morning in Scotsman’s Bay, Dun Laoghaire, followed by a cycle from Dun Laoghaire via the Coast Rd, Tom Clare Bridge, the North Quays, Parkgate St and Infirmary Rd before entering the Phoenix Park at the North Circular Rd Gate. The cyclists will exit the Park at White’s Gate and continue via the Luttrellstown Rd, out to Dunboyne, then to Kilcock, Maynooth, the Strawberry Beds and back into the Phoenix Park where the run takes place and the Ironman will finish. There will be various road closures in place to facilitate the event so traffic disruption is highly likely.
