Glendalough Lap of the Gap Marathon & Glen to Glen Half
The event is organised by Glendalough AC and runs inside Wicklow Mountains National Park between Glendalough and Laragh. The 2027 edition is the tenth running and includes two distances:
- 42.2 km with about 800 m of climbing
- 21.1 km with about 340 m of climbing
Both races start near the Upper Lake in Glendalough and finish in Laragh village. The marathon route climbs from the valley floor, passes Glenmacnass Waterfall, crosses the Sally Gap, skirts Lough Tay, and descends through Drummin and Oldbridge before arriving in Laragh. The course profile shows sustained climbing in the first 11 km and a fast descent from around 27 km.
Race day operations are centred at Race HQ in Upper Lake Park, which hosts registration, helpdesk, toilets, bag drop and a key box. Private vehicles cannot drive to the Upper Lake road. Transport options to Race HQ include a direct coach from Dublin, a free shuttle from Laragh GFC, an approved drop-off near the Glendalough Hotel, or a 3.5 km walk from Laragh village. Aid stations are provided at set intervals with semi-self-sufficiency required on higher ground. All competitors finish in Laragh where bags, food and return coaches are based.
Places are limited and released in three pricing phases. Visit the organization's website for the most recent information.
