South Downs Way
The South Downs Way is the only National Trail that can be run or cycled in its entirety — 160 km from Winchester in Hampshire to Eastbourne in East Sussex along the chalk ridge of the South Downs.
About South Downs Way
The South Downs Way runs the full length of England's newest national park, following the ancient chalk ridge of the South Downs from the cathedral city of Winchester to the chalk cliffs at Beachy Head near Eastbourne. It is one of the most accessible National Trails — well-surfaced, well-waymarked, and within an hour of London — and it has become a popular multi-day running route for those building into longer challenges.
The route is entirely off-road and follows bridleways, byways and open downland throughout. The chalk surface drains quickly after rain and the paths are largely firm underfoot even in winter, making this one of the more runnable National Trails year-round. The ridge gives long views north over the Weald and south to the English Channel for much of the route.
Trail runners typically complete the Way in one to three days. The South Downs Way 100 race covers the full distance in a single stage. Most recreational runners take two long days, with an overnight in Petersfield, Amberley or Lewes.
The scenery is pastoral and quintessentially English — dry valleys, dewponds, yew woods, downland villages and the constant presence of the sea in the southern distance. The Seven Sisters chalk cliffs near the finish are one of the most recognisable landscapes in southern England.
The route
Winchester to Petersfield (~50 km): A gentle start through chalk downland east of Winchester. Butser Hill (270 m) is the highest point on the route. The terrain is open and fast.
Petersfield to Amberley (~50 km): The Sussex Downs begin in earnest. Harting Down, Upwaltham Hill, Bignor Hill. Good ridge running with views both north and south. The River Arun crossing at Amberley is a useful halfway food stop.
Amberley to Lewes (~40 km): Chanctonbury Ring (Iron Age hillfort), Ditchling Beacon (248 m) — the highest point on the route east of the Marne. The area around the Beacon is the most popular day-walk on the entire South Downs.
Lewes to Eastbourne (~25 km): Firle Beacon, the Cuckmere valley, the Seven Sisters chalk cliffs. The final section to Eastbourne passes through the most dramatic coastal scenery of the route.
Getting there & logistics
Start: Winchester city centre, King Alfred's statue. Winchester has a main line train station with regular services to London Waterloo (1 hour) and Southampton.
Finish: Eastbourne seafront. Eastbourne has a train station on the Connex South Eastern network, with services to London Victoria (90 min) and Brighton.
Accommodation: Winchester, Petersfield, Amberley, Lewes and Eastbourne are the main centres. YHA hostels at Arundel, Telscombe and Eastbourne. Camping is allowed at several designated sites along the route.
Best time: Year-round. The chalk surface drains well and running is possible in most conditions. Spring and autumn give the best light and fewer visitors. The South Downs Way is busy in summer, especially near Ditchling Beacon.
Safety
The South Downs Way is the most benign of the National Trails — no high mountain terrain, no serious river crossings, good paths throughout. The main hazards are exposed ridge walking in high winds and disorientation in sea mist on the eastern section.
The Seven Sisters cliffs near the finish are unfenced and very dangerous — stay well back from the cliff edge. Several people have died in falls from the chalk cliffs in recent years.
In an emergency: call 999 or 112. The South Downs are well covered by road access and emergency services. For coastal incidents near Eastbourne, ask for Coastguard. Pre-register SMS 999 (text 'register' to 999) as a precaution.
