Naseby 1645 2027

Naseby 1645 is a 16.45-mile road race held in rural Northamptonshire, beginning and ending at Naseby Village Hall. The unusual distance is intentional: 1645 marks the year of the Battle of Naseby, and the race adopts this number for its identity. This is an entirely road-based event on quiet country lanes, featuring an undulating course that requires more than just flat-speed fitness. The race occurs during the spring marathon build-up, attracting runners seeking a substantial, structured test before focusing on 26.2 miles. The route includes seven memorials and viewpoints associated with the Battle of Naseby, weaving a local history narrative into the run beyond a simple loop through the countryside. Road closures are in effect for a significant portion of the course, with marshals and support provided. Participants should be prepared for the distance before entering. A four-hour cut-off is in place, race numbers with timing chips are distributed on race morning, and the event consistently sells out annually.
