The Semi-marathon de Plouguin is held on November 11, starting at the sports hall in Plouguin, a small commune in Finistère, Brittany. AS Plouguin organizes this annual event, featuring a 21.1 km half marathon, a 10 km race, a half marathon duo relay, and a walking option. The race has taken place every year since 1979. Recent editions have attracted just over 200 participants, unlike large city races.
The course is described as a road race, but local details suggest more variation than a simple out-and-back. It follows paths through the Plouguin area, incorporating coastal sections and wooded stretches. The half marathon begins in the afternoon, and bib collection is available shortly before the start. The atmosphere is local and relaxed, intended for runners who wish to share the challenge and run at their own speed.
