The Great Herts AONB Event 2027

The Great Herts AONB Event takes place on 6 June 2027 in Gosmore near Hitchin, Hertfordshire. The event runs separate categories for runners and riders who use the same routes through countryside tracks and trails within the Chilterns Area of Outstanding Natural Beauty.

Courses vary from flat to undulating and hilly in places. All races start and finish on the Gosmore village green, with Maydencroft Lane serving as the actual start line to allow a mass start. Parking is provided about two to three minutes' walk from the race village and toilets are available at Race HQ at the Bird in Hand Pub. A children’s Runners and Riders event is held on the village green while the main routes are underway, and some proceeds support chosen charities.

Distances offered include:

  • Tough Ten 10 km for ages 16 and above
  • Hard Half 13.1 miles (21.1 km)
  • Mighty Marathon 26.2 miles (42.2 km)

Riders set off before runners for each distance. Included elements for 2027 comprise a race bib with integrated timing chip, electronic timing and live results, a race village with food and stalls, child and dog friendly routes, baggage drop, bespoke finisher medal, optional T shirt purchase at £15 with marathon runners receiving a free shirt, awards, downloadable finisher certificate, drink and water stations with snacks on the half and marathon routes, medical provision, fully signed course, marshals, printed route maps and downloadable GPX files.
