Seven Sisters Skyline Ireland

The Seven Sisters Skyline Ireland is an epic mountain running challenge set amidst the rugged and mystical landscapes of Donegal. This 55km race, featuring a staggering ascent of 4,100 meters, is widely regarded as one of the toughest mountain events in Ireland. The course winds through the Derryveagh Mountains, also known locally as "The Seven Sisters," each peak offering its own unique Gaelic name and character.
Starting from Dunlewey, a quaint Gaeltacht village nestled at the foot of Mount Errigal—the highest point in Donegal—runners traverse unspoiled wilderness that rivals scenes straight out of fantasy literature. The terrain is varied and demanding, with steep ascents and descents across seven distinct peaks, each presenting its own challenges.

Just a short journey from bustling cities like Dublin and Belfast, the race offers an escape into nature where runners can experience some of Europe's most spectacular coastal views and rugged mountain vistas.
Whether you're tackling the full 55km or one of the shorter options available, this event promises to be an unforgettable adventure through Ireland’s coolest corner.
