The SDW50km is a 50km non-stop foot race through the South Downs National Park. The South Downs boast stunning rolling hills, ancient forts, picturesque villages and expansive views across Southern England. This is the inaugural event.
The course travels along the chalk ridgeway, starting just outside of Winchester, the capital city of Saxon England, in the incredible natural amphitheatre of Matterley Bowl. The course sits entirely within the South Downs National Park with the majority on the South Downs Way National Trail - until the finish in the Event Field at Queen Elizabeth Country Park at the foot of the screaming fast descent off of Butser Hill. The South Downs tower over Southern England affording runners awe inspiring views north across the Weald and south across the coast and the Channel. Runners will be fully supported by four well stocked aid stations, full medical support and a fully marked course. 9 hour cut off. Race held under full UK Athletics Permit granted through the TRA (Permit Number Pending).
