Lambton Castle Summer Trail Runs 2026

The Lambton Castle Summer Trail Runs are off-road races held within the private grounds of the Lambton Estate, located near Chester-le-Street in County Durham. The series provides 5, 10, and 15 mile options, all starting at 10:00 AM. This allows participants to select a shorter trail run or a longer morning event across varied terrain. The routes incorporate rough trails, firm paths, and cross-country-style fields, deviating from a standard road loop. The primary appeal is the private estate setting, granting runners access to grounds not typically available for training. Past results indicate the event has seen multiple editions with returning participants.
