Shires and Spires

Shires and Spires is a multi distance running event based at Naseby Village Hall in Northamptonshire. The route uses both road and trail sections and passes local landmarks such as Holdenby House, Althorp House and Cottesbrooke House. The event received the MARM Race of the Year award in 2023.

The course direction changes each year: on even years the route runs clockwise and on odd years it runs anti clockwise. Distances include a mix of road and trail mileage and varied elevation profiles. Navigation requirements and support differ by distance.
