Graef Castricum Trail & WALK 2026

Graef Castricum Trail & WALK is a trail running and walking event in the Noordhollands Duinreservaat near Castricum, Netherlands, held at the start of winter. It offers a wide spread of distances, from a 1.5 km Kidstrail to an Ultra 60 km, with intermediate routes of 7, 11, 23, and 35 km. The programme includes TRAIL, WALK, Canitrail, and Kidstrail options, making it an event for more than just runners. The routes utilize the landscape around Castricum: beach sections, dunes, forest, unpaved paths, winding single tracks, and stretches along lakes. The longer distances provide a full coastal-dune outing, while the shorter walks and trails keep the event accessible to families and less experienced participants. CAIRN Trails & Adventures organizes the event, and this Noord-Holland CAIRN TRAIL edition is part of a series that emphasizes self-paced off-road effort over road-race speed.
