Norn Iron 100

Embark on an unforgettable 106-mile ultra marathon along Northern Ireland's breathtaking Causeway Coast. This epic journey begins in Ballintoy and follows the iconic Ulster Way, winding through some of the most stunning landscapes in Europe.
From the rugged cliffs of Portrush to the serene beaches of Ballycastle, runners will traverse a diverse range of terrain including bogland, forest trails, open roads, and even the legendary Giants Causeway. The route offers unparalleled views across the North Coast’s dramatic coastline, with its towering sea stacks and rolling green hills.
As you progress through towns like Portstewart and Castlerock, the scenery evolves to reveal the lush Glenshane Pass and eventually the Sperrin Mountains before reaching your final destination in Gortin, County Tyrone. This self-navigated adventure is designed for experienced trail runners seeking an authentic connection with nature.
Participants will receive a detailed GPX file of the route but should be prepared for minimal support along the way—no additional signage or marshals are provided to keep the experience as natural and challenging as possible. This race is not just about reaching the finish line; it’s about immersing yourself in Northern Ireland's wild beauty.
