Nephin

Lahardaun, Ireland • 20 Jul 2025

Nephin is a challenging mountain running event held in County Mayo, Ireland, organized by the Irish Mountain Running Association. The race features a 7.35 km out-and-back course ascending 736 meters via a recently established waymarked path to the summit of Nephin. The terrain is difficult, with steep gradients and loose stones, requiring caution, especially on descent.

Participants must adhere strictly to the marked route, which includes navigating a stile over a barbed wire fence. The event offers a shorter 5 km option turning at the mountain base.
