Delphi Half Marathon

The Delphi Marathon, Half Marathon & 10K on 15 May 2027 is on a breathtaking course from County Mayo to the heart of Connemara.

New in 2027, the full Marathon will be on a mixed-terrain course, with route details to be confirmed.

The Half Marathon starts at Glenkeen Farm, Mayo on a point-to-point route that finishes in Leenane, Connemara. It is a mostly downhill route with a few gentle rises and competitors enjoying fjordside running with mountains on one side and Atlantic waters on the other.

The 10km is a shorter version of the Half Marathon that starts just beyond Delphi, Mayo and finishes in Leenane. It is mostly downhill and flowing, ideal for all levels.
