Why run it?
The Antrim Coast Half Marathon is one of the fastest half marathons in the world and has set four UK & Ireland All-Comers Records since the event started in 2020. The half marathon route, which takes you on a journey through Antrim's spectacularly scenic coastland, is essentially flat with a downhill at 1,300 metres to go, sweeping off the Coast Road onto Larne Promenade. You'll be running along one of the world’s most beautiful coastlines with the chance to set a new PB or just enjoy the magic of this naturally breathtaking half.
