The Brentwood Half Marathon is the largest event of its kind in Essex and a fixture of the UK running calendar since 1982. The race attracts thousands of runners each spring with its well-organised, community-driven approach. The 13.1-mile (21.1 km) course is gently undulating yet fast, making it ideal both for athletes chasing personal bests and those preparing for the London Marathon. Runners benefit from chip timing, professional medical support, extensive pacemaker groups, and a supportive atmosphere along the route. Finishers receive a quality medal made from 100% recycled zinc, with optional commemorative T-shirts available. The event holds a BARR Gold Standard rating, with proceeds donated entirely to local, national, and international charities.
