Seaford 10K

Where the South Downs meet the sea, the Seaford 10K on Sunday, 10th May 2026 offers a uniquely invigorating coastal challenge. Starting at the historic Martello Tower, this accurately measured out-and-back course delivers crisp sea air and breathtaking vistas with every stride along the Esplanade pathway. More than just a fast, EA-affiliated race, it’s a full-sensory experience—the rhythmic crash of waves provides a natural soundtrack as you push toward Newhaven and back, fuelled by the vibrant support of the local community. Organised by MCC Promotions in support of the RNLI Newhaven Lifeboat, the event captures the raw, natural beauty of the Sussex coastline in a uniquely accessible format. Come for the potential personal best, stay for the unforgettable atmosphere and a bespoke medal that commemorates your run between the downs and the deep blue.
