Antrim Coast Half Marathon

The Antrim Coast Half Marathon hugs Northern Ireland's dramatic coastline with breathtaking scenery. Runners trace the famous Causeway Coastal Route, with the Irish Sea's crashing waves on one side and rolling green hills on the other. August's unpredictable maritime weather adds an element of challenge as participants follow a predominantly flat course with occasional gentle rises. The route passes historic castles, charming fishing villages, and the stunning Glens of Antrim, offering continuous visual reward. Irish spectators bring genuine warmth and enthusiasm, creating an atmosphere that balances serious competition with Celtic hospitality. This increasingly prestigious race captures Northern Ireland's distinctive character—naturally spectacular, historically rich, and genuinely welcoming—offering both world-class competition and immersion into one of the UK's most dramatic landscapes.
