Art O'Neill Challenge

THE MIDDLE: OF THE NIGHT, OF NOWHERE

On September 26th, 2025, the Art O’Neill (AON) will once again escape from Dublin Castle. In the escape of 1592 the Castle wardens gave chase, but gave up due to poor weather.

The event will start from Dublin Castle heading out through South Dublin , eventually passing Stone Cross and eventually continues over open mountain via Art’s Cross to its finish at Glenmalure. The event is fully supported, with Dublin & Wicklow Mountain Rescue Team at hand should help be needed.

Entries are capped at 200.
