The Art O’Neill (AON) Challenge on 26 September 2025 is a 60km road and mountain race from Dublin Castle to Glenmalure.
The AON Challenge is suitable for both runners and walkers. There is also the AON Pursuit, a shorter 25km road race from Dublin Castle to Kippure Estate which is suitable for runners only.
Both events will start from Dublin Castle and follow the same route through Dublin to Kippure Estate. The Pursuit will finish at Kippure Estate and the Challenge continues over open mountain via Art’s Cross to its finish at Glenmalure.
Places for the Challenge event are decided by lottery. Both events are fully supported, with Dublin & Wicklow Mountain Rescue Team at hand should help be needed.
