Norn Iron 100

About the Event

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.
Experience the awe-inspiring vistas, rugged terrain, and rich history of this unique point-to-point ultra marathon.

About Ballycastle

Learn more about the host city, Ballycastle.

Scenic view of

Ballycastle is a fishing port and beach resort in County Antrim in Northern Ireland. Those counties are no longer units of government so the town is now in Causeway Coast and Glens District, and in 2021 had a population of 5600. It's close to the top-draw attractions of Giant's Causeway, Carrick-a-Rede Bridge and Dark Hedges, all very touristy, but has many others that escape the hordes. The town is named for its own castle, lost somewhere beneath Castle Street, but others still stand on dramatic headlands, and Fair Head is a natural wonder.
