Larmer Tree Marathon, 20 Miler, Half Marathon & 10K 2027

The Larmer Tree races start and finish at Larmer Tree Gardens on the Rushmore Estate, with spring trail races across the Wiltshire Downs. The series is family friendly and offers several distances: 7 miles, 10 miles, half marathon, 20 miles, and marathon. Dog-friendly 7-mile and 10-mile options are also scheduled. The routes use the private Rushmore Estate grounds, giving the event a country-estate feel. Runners should expect hills, and the ground can be muddy after wet weather. Shorter routes are suitable for newer trail runners, while the half marathon and 20-mile races are good for those building toward marathon season. Larmer Tree Gardens has been described as one of Britain’s poshest race venues, an unusual base for a muddy spring trail weekend.
