About
The Demi-marathon d'Abersoch is a half marathon in Abersoch, Wales, on 11 September 2027, on a route that hugs the coastline with regular sea views throughout its 21 km.
The course makes the most of the sea air of this Welsh coastal area, between cliffs and unspoilt natural scenery typical of the Llŷn Peninsula. The wind, often present on this stretch of coast, adds an extra challenge to factor into race strategy, especially on the most exposed sections.
This road race is aimed at half marathon runners looking for a seaside setting for a distance that sits between the 10K and the marathon.
