Chichester Festival of Running 2026

The Chichester Half Marathon on 4 October 2026 features a 21.1km mixed terrain race and a 12km trail run. The routes combine historic city streets with the rolling countryside of West Sussex, offering scenic views. Both races start in Chichester. The Half Marathon follows a partially closed road course past landmarks such as the Cathedral, The Cross, and the Roman Walls. Runners then transition to the South Downs for the trail sections, which include rolling hills, varied off-road paths, woodland trails, and moderate climbs.
