The Leigh-on-Sea 10k is an after-dark, multi-terrain running event held in Leigh-on-Sea, featuring both 10k and 5k distances, including a juniors' 5k for ages 11-15. Scheduled for early November, the race offers a spooky Halloween-themed atmosphere with mandatory head or body torches and optional fancy dress, which can earn participants a bonus prize. The course showcases the best of Leigh-on-Sea and emphasizes safe night-time running with ample marshals. The event is chip-timed, promotes sustainability, and each finisher receives a unique "not medal" prize and a glass of prosecco.
