Quadrathon Challenge - course overview
The Quadrathon Challenge is a four-day running event around Inishowen, Donegal, Ireland, staged 12 to 15 August 2027. Over four consecutive days participants cover four separate courses that together form a single coastal loop of about 105 miles. Races are offered each day as a full marathon option and a half marathon option on different routes.
Each day uses distinct coastal roads on the Wild Atlantic Way with varied terrain and elevation changes. Course surfaces are predominantly tarred road. Organisers note significant climbs on some days, for example a 900 ft climb on Day 1 and an 880 ft climb at Mamore Gap on Day 3, and advise allowing extra time compared with flat marathon times to account for elevation and consecutive-day running.
Daily course highlights:
- Day 1 Kinnego: scenic coastal stretches, a tough 2 mile climb, finish near Kinnego Bay.
- Day 2 Malin Head: northern coastal roads along the Wild Atlantic Way with exposed coastal views.
- Day 3 Mamore: generally flatter sections punctuated by Mamore Gap climb and a shore path finish into Buncrana.
- Day 4 Muff: mainly flat final day along Lough Swilly and the River Foyle toward Moville.
Event features include separate start times for walkers and slower runners, roadside aid at half marathon stages, catering at finish areas, shower facilities at some clubhouses, and medals for finishers. Visit the organization's website for the most recent information.
