The Kimbolton Castle Half Marathon starts and finishes at the magnificent Kimbolton Castle which is set in a small village between St Neots and Northampton.
The course follows an undulating but scenic all road route, which passes through Tilbrook, Upper Dean, Risley and Swinshead before heading back to Kimbolton. You will run on the left at all times. Be advised this is not a traffic free route. Take care!
