Chelmsford Marathon & Half Marathon 2026

The Chelmsford Marathon & Half Marathon begins at 9:00 am in Chelmsford, Essex. Both distances follow accurately measured, undulating road courses. This autumn race offers a marathon or half marathon option and attracts over 1,500 participants, establishing it as a significant event on the Essex race calendar. A six-hour cut-off defines the marathon structure, and pacers are typically available for both distances if sufficient numbers are confirmed. The route departs Central Park via tree-lined avenues, then proceeds onto rural country lanes. This provides participants with a blend of town running and Essex countryside, distinct from a city-centre circuit. The courses are frequently chosen for good-for-age qualifying attempts, though their undulations prevent them from being a flat time-trial course. A substantial aspect of the race involves fundraising for Little Havens Children's Hospice and Havens Hospices, organizations supporting individuals with complex or incurable conditions. Runner contributions generated over £53,000 in a recent running. Participants can select a HAVENS HEROES ticket, which incorporates a donation, and the race also relies on hospice supporters and marshals within the event village.
