The Windsor Trail Run Half Marathon & 10K is a November running event in Windsor, Berkshire, offering both 10 km and 21.1 km distances. It begins in Alexandra Gardens, near the Thames and with views of Windsor Castle, providing a more specific setting than a typical park run or road race. The 10K starts first, with the half marathon following soon after.
The course follows paths through Alexandra Gardens on a flat trail, making it suitable for new runners or those aiming for a consistent time. Its appeal lies in the straightforward format: two distances, a central Windsor start, and castle views in a historic town. Lucy Harfield is the organiser.
