Glendalough Lap of the Gap Marathon

The Glendalough Lap of the Gap Marathon takes place in the Wicklow Mountains National Park on Saturday 23 May 2026 and is organised by Glendalough AC. Promoted as Ireland's highest road marathon, the race offers long views across upland country and a route that links the monastic village of Glendalough with Sallygap and Laragh. The event emphasises a scenic experience combined with a physically challenging course and a strong local club ethos. Entrants are directed to the official event website for key information, the competitor handbook and entry details.

The marathon is notable for its sustained elevation changes and varied road terrain rather than technical trail running, making it a distinct road marathon within a national park setting. Historic results, race rules and registration links are published on the event site and retained in the event archive for past editions. Competitors should consult the official site for course maps, exact start logistics and any updates prior to race day. The race supports the local athletics club and sits alongside a half-marathon offering on the same day.
