Join us on Sunday, 28th September 2025, for one of the best-loved half marathon and 10K races in Sussex. It’s a full programme, with the third year of the 5K race, starting at 9.55am, the Half Marathon at 10.05am and the 10K at 10.25am. Kids aged 4-11 can participate in the Kids Colour Run – Jennings Junior Jog at 12.30pm. Our senior races feature closed roads, chip timing, pacers, and medals for all finishers. Stay hydrated with water stations on the 10K and half marathon routes. Free parking, scenic views, and a professional warm-up await. Road closures start at 9.30am, so arrive early! This award-winning event is run entirely by volunteers and continues to support St Catherine’s Hospice in 2025. Train and challenge yourself this September at Run Barns Green!
