Dark Skies Run @ Wooler Half Marathon & 10K 2026

The Dark Skies Run @ Wooler begins at Wooler Youth Hostel in Wooler, Northumberland, leading into Northumberland National Park. This trail race offers 10K and half marathon distances, scheduled for late October. Trail Outlaws is the organizer. The half marathon is considered one of the UK's most challenging trail halves. The courses are clearly marked, and participants receive well-supplied checkpoints instead of a self-supported format.
