The Half Marathon is a unique opportunity to run, walk or jog in the spectacular and scenic surroundings of Inis Mór and to soak up the atmosphere, ceol and culture that the island has to offer. For more than 20 years, the Aer Arann Islands Half Marathon has supported worthy causes. We are honoured to work with the Marathon Committee to raise the funds to enable us to transform and improve patient care in The Mater Hospital, which provides expert, specialist treatment to hundreds of thousands of sick people and their families from all across Ireland each and every year.
