About the Event

Join the vibrant running community for an unforgettable experience at one of Essex's premier racing events, taking place on Sunday, October 11th. This highly acclaimed race offers both marathon and half-marathon distances through picturesque landscapes that highlight the beauty of Chelmsford.
The event is renowned not only for its challenging yet scenic routes but also for fostering a warm and supportive atmosphere among participants. The course winds through Central Park's lush tree-lined avenues before venturing onto rural country lanes, offering runners stunning views throughout their journey. Both courses are accurately measured and undulating, making them ideal for those seeking to qualify in age categories.
The race day is enhanced by the presence of enthusiastic marshals who cheer on participants every step of the way. The event village features a variety of amenities designed to cater to all athletes' needs before and after their run. In addition to the well-organized facilities, runners can look forward to receiving bespoke medals upon completion and trophies for top finishers.
A key highlight this year is the partnership between Little Havens Children's Hospice and the Carli Lansley Foundation, providing free heart screening for younger participants at no extra cost. This initiative underscores the event’s commitment to supporting local communities and raising awareness about vital health services.
Choosing a "Havens Hero" entry option means contributing £16 towards Little Havens' mission of delivering specialist care and support to children with complex or incurable conditions, helping families cherish every moment together.
With its friendly atmosphere and strong community spirit, this race is more than just a run; it’s an opportunity for runners to make a meaningful impact while enjoying some of the best autumn scenery Essex has to offer. Don't miss out on being part of something truly special!
