Stretching 50 kilometers along Northern Ireland’s rugged Causeway Coast, the Causeway Coast Ultra Marathon in Portrush challenges your endurance against a backdrop of dramatic cliffs, roaring seaside winds, and forest paths that keep you alert underfoot. The route offers 900 meters of cumulative elevation gain—steady but never overwhelming—making it accessible for seasoned ultra runners and ambitious trail enthusiasts alike. From the green expanses of water-glistening forest tracks to rocky promontories that dare you to push forward, each kilometer delivers a new sensation of raw, untamed Northern Irish terrain.

Terrain varies sharply: expect a demanding mix of rocky shorelines where the Atlantic surf crashes insistently, gravel paths that mimic the steady breath of the land, and sections of sandy stretches that test your foot placement and pace. Forested stretches—where imposing pines stand like quiet guardians—provide brief respite as you navigate roots and loose soil. The wind off the ocean challenges you steadily, as if nature itself is reminding you this course is fiercely itself, never yielding.

Preparation is key. Hydration isn’t just advice here—it’s essential. Carry a hydration pack or plan water stops strategically; aid stations are thoughtfully positioned but don't rely on them exclusively. Good trail shoes with firm grip and responsive cushioning will protect your ankles and feet from the rocky coastal paths and uneven forest floors. Timing your run early in the morning or late afternoon helps you beat the strongest winds and catch softer light, which not only eases the physical challenge but pumps up the experience.

Finish lines aren’t just a relief; they’re a celebration. Portrush welcomes its ultramarathoners with the town’s coastal charm. Whether you cool down with a walk along the peaceful East Strand Beach or refuel in one of the town’s cozy cafés, you’ll find the local atmosphere quietly rewarding after the physical test.

This event is a merge of rugged challenge and thoughtful design. If you're after a race that tests your limits without demanding technical mastery, with memorable views and a course that listens to its coastal setting, this is it. Gear up, respect the terrain, and let the Causeway Coast push and pull you along its fiercely beautiful stretch.
