Race Info
The Half Marathon at Goodwood Motor Circuit covers 21.1 kilometres, or 13.1 miles, on the home of the Festival of Speed and Goodwood Revival near Chichester. Runners complete measured laps inside the historic perimeter road, on smooth closed tarmac with kilometre markers and no traffic. The course is essentially flat, and the repeated laps make it easy for spectators to follow runners from the event village.
