Hertfordshire Half Marathon & 10K November

The Hertfordshire Half Marathon & 10K is a road race held in early November, starting in Old Knebworth. It offers two distances on the same day. The half marathon provides a longer autumn goal for regular runners, while the 10K is suitable for those seeking a shorter challenge or progressing to a longer distance. Both courses follow rolling roads through the Hertfordshire countryside, differing from a flat city race. The event benefits Garden House Hospice Care, which delivers free specialist palliative care to patients, families, and carers throughout North Hertfordshire, Stevenage, and neighbouring areas in Central Bedfordshire and Cambridgeshire.
