Ardgillan takes place in Ardgillan Demesne, County Dublin on Wednesday 20th May 2026. The event is organised by the Irish Mountain Running Association and offers a main trail race and a shorter junior course inside the park.

Distances

• 9.50 km main course, approximately 190 m climb
• 5.00 km short course and junior course inside the park

The route is fully marked and GPS is allowed. The course runs through the demesne with rolling hills, runnable climbs, a firm sand beach section, and the local Parkrun finish hill. Views of the Mourne Mountains are possible in clear conditions. The junior course omits the bridge and beach sections and finishes at the same location as the main race.

All entrants must bring the required items; the final kit to be carried may be advised at registration and random kit checks may be carried out. Failure to have required items may lead to denial of entry or disqualification.
