The Westonbirt Arboretum Half Marathon, 10K and 5K take place within Westonbirt, The National Arboretum in Gloucestershire. The routes explore a remarkable landscape containing thousands of trees from around the world, creating a distinctive setting for a multi distance running event.
Runners can choose the half marathon, 10K or 5K, with routes held predominantly on solid stone forest paths and only gentle rises and falls. The firm surfaces provide running conditions closer to a road course while retaining the scenery of a trail race, with comprehensively marked routes and marshals positioned around the course.
A 1 mile fun run provides a shorter option for participants of all ages, making the event suitable for families as well as experienced runners. Finishers receive an event medal, while the arboretum provides plenty to explore beyond the races and can be enjoyed by runners and spectators after finishing.
