Race Info
The Chelmsford Marathon is a single-lap road race that starts and finishes in Central Park, Chelmsford, Essex, running through the park's tree-lined avenues and out into the surrounding Essex countryside. A half marathon runs an out-and-back course on the same morning, starting half an hour after the marathon's 9:00 AM gun. The race has run each October since at least 2016 and raises funds for Little Havens Children's Hospice.
