David O Connor is an Irish ultra-endurance athlete.   The events he has been involved in have included running 10 marathons in 10 days on an athletics track (260 miles/1055 laps), running 247km in one weekend around Dublin, cycling 200km from Cork to Wicklow on a child’s BMX and climbing Lugnaquilla (the highest peak in Leinster) with 55lbs on his back. Many of these challenges symbolize mental health struggles — the heavy load accompanying him on the mountain climb, for instance, represented “the burdens we carry on our minds and the pressure we put ourselves under every day”.
