8k Run Arun: Scenic Loop Through Arundel Park

Route Overview & Local Insights

This 7.6km loop offers a quintessential South Downs trail running experience, trading asphalt for the undulating grass tracks and woodland paths of Arundel Park. Starting from the serene Swanbourne Lake, you’ll tackle a hiller terrain with 134m of ascent that rewards your efforts with sweeping views of the Arun Valley. The course takes you through the shaded canopy of Lonebeech Plantation before opening up into the expansive, rolling hills of the estate. Expect a mix of soft turf and chalky trails that can become slick after rain, making it a perfect route for those looking to build strength on varied, "category 3" hilly terrain while enjoying some of West Sussex's finest off-road scenery.

Steeped in history, Arundel Park is the private backyard of Arundel Castle, the ancestral home of the Dukes of Norfolk for over 850 years. As you run, keep an eye out for the ancient Hiorne Tower—an 18th-century triangular folly that stands as a landmark for local navigators. The area is a haven for wildlife, and it is common to spot red kites circling overhead or a herd of fallow deer grazing near the treeline. Running here feels like stepping back in time, away from the bustle of the town, providing a peaceful yet challenging escape into the heart of the South Downs National Park.
