Kimbolton Castle Half Marathon – Sunday 15th August 2021

Kimbolton Castle Half Marathon


Join us in the majestic surroundings of Kimbolton Castle for a half marathon. Entries are strictly limited to 800.

Kimbolton Castle, a country house in Cambridgeshire, was the final home of King Henry VIII’s first wife, Catherine of Aragon. Originally a medieval castle, it was converted into a stately palace in 1690, which now houses Kimbolton School.

The race starts in the grounds of the castle and heads through Kimbolton High Street and the villages of Tillbrook, Lower Dean, Upper Dean and Swineshead, before returning to Kimbolton Castle and an iconic finish in front of the stately palace.

Kimbolton High Street will be opening up their amazing stores on the race day, and we’d love it if spectators cheer on the runners and support this beautiful village high street.

No matter if you are preparing for an Autumn Marathon or simply looking for a beautiful, scenic run, this traffic-free half-marathon is perfect for you.
