Glendalough Lap of the Gap Marathon

About this event

The Lap of the Gap marathon and half-marathon takes runners through County Wicklow's dramatic highlands, starting from Laragh village and climbing towards Sallygap pass. The route combines steep ascents with flowing descents, passing Lough Tay (known locally as Guinness Lake for its dark waters) and winding through heather-covered moorland near Glenmacnass Waterfall. Both distances loop through the historic monastic site of Glendalough, where ancient stone towers rise from wooded valleys. This is proper mountain running on tarmac — expect serious elevation and exposed highland terrain. The half-marathon offers a taste of the full circuit for those building towards longer efforts.
