The Inis Oírr Wild Atlantic Island Run 5k is an annual road race held on Inis Oírr (Inisheer), the smallest of the Aran Islands off the west coast of Ireland in Galway Bay. The race starts and finishes at Páirc Peile Inis Oírr and takes runners along the island's quiet roads and boreens, passing iconic limestone landscapes and offering stunning views of the Atlantic Ocean and the Cliffs of Moher. The course is a loop around the island's scenic roads on tarmac. The event raises funds for Coláiste Ghobnait, the local secondary school, and attracts runners who combine the race experience with the unique character of island life.
