The Glendalough Lap of the Gap Marathon is the only road marathon event held in the Wicklow Mountains National Park. The event – and it’s little brother the ‘Glen to Glen Half-marathon’ – have been held since 2016 by local club Glendalough AC on the penultimate Saturday of May before the peak tourist season in the area.

The races offer a unique challenge: hilly and tough but also beautiful and scenic. You are unlikely to find personal bests on our courses but guaranteed an experience to savour and a challenge to be proud of. During the race you can savour some of Wicklow’s main natural sights including the Glendalough Lakes, the Glenmacnass Waterfall, and Lough Tay (the ‘Guinness Lake’).

We pride ourselves on offering a race that is both an experience for the casual runner but also a true sporting competition for the competitive or elite entrant.
