A five-distance circular event that has something for everyone. The event features a mixture of trails and roads over 10k (roads), half-marathon, three-quarter marathon (new in 2025 for anti clockwise!), marathon and ultra marathon distances.

All the race options start and finish at Naseby Village Hall, nestled at the heart of the quaint village of Naseby – made famous as the home of the Battle of Naseby in 1645, a major scuffle during the English Civil War.

Naseby is a fantastic central location, with easy access to the A14, M1 and M6. From there, the route takes runners across the Northamptonshire countryside, with the multi-terrain marathon and ultra taking them past a host of country houses. Expect to see Holdenby House, Cottesbrooke, and Althorp – the home of the Spencer family and final resting place of Princess Diana.
