MTC Shamrock

MTC Shamrock is a 50-mile ultramarathon on Ireland’s west coast, new for 2026 and part of the Mount to Coast End to End Challenge, also serving as Day 4 of MizMal®. The race runs from Cliff House Hotel, Ballybunion to the Limerick City Hotel, largely following the MizMal route along the Wild Atlantic Way. It features about 1,550 ft of ascent and 1,616 ft of descent, demanding steady endurance.

Finisher perks include a bespoke medal, with optional race shirt and hi‑viz jacket. The cup-free event caps at 40 entries (plus MizMal competitors), enforces 4 mph cut-offs, and provides maps and real-time tracking for entrants, four weeks before the event.
