Clontarf Half Marathon

Dublin's most scenic Half Marathon

Run one of Dublin's most beautiful coastal routes. Starting and finishing at EastPoint Business Park, the Clontarf Half Marathon takes you along the Clontarf Promenade and across Bull Island, with uninterrupted views of Dublin Bay and Howth Head the whole way round.

Every year this race sells out. Every year runners miss out. Don't be one of them.
