The Art O'Neill Challenge is an awesome 55k night hike /run, leaving Dublin Castle at midnight on Friday January 15th 2016, and finishing in Glenmalure Valley the following day. Ultra run starts 1 hour later. It retraces the epic route taken by Art O'Neil and Red Hugh O'Donnel in 1592. On January 6th, 1592 Art O’Neill, his brother Henry, and Red Hugh O'Donnell made a bid for freedom from Dublin Castle. It was the middle of winter and Ireland was held fast in its icy clutches but they hoped to reach the relative safety of the remote Glenmalure Valley over 50km away. Ill equipped and underfed they were the only prisoners ever to successfully escape captivity from Dublin Castle but it was an ill fated journey with Art O’Neill dying from exposure only miles from his goal. Previously a commercial event the Art O'Neill is now a fund raising event for the Dublin & Wicklow mountain rescue team.
