TOUGH HIKE 38K Challenge - Lewes to the coast AND THEN the Seven Sisters

TOUGHNESS WARNING – Are you sure this is right for you?
This is our longest ever London day hike, and it is suitable only for very fit, fast and experienced hikers. At almost 38 km with 1,000 m of total ascent, this is a demanding endurance challenge involving repeated steep climbs and descents. The pace will be consistently brisk in order to complete the full route and arrive in Eastbourne in time for the return train.
To ensure fairness and safety for all participants, anyone unable to maintain the required pace or complete the route will be asked to leave the hike and make their own way to Eastbourne. The final section passes several bus stops with services to Eastbourne, providing options to shorten the route if needed.
If the prospect of climbing the equivalent of over three times the height of The Shard over nearly a marathon-length distance does not appeal, this event is not suitable for you. Please register only if you are confident in your fitness, experienced at this level, and genuinely motivated by a challenge of this scale.

🥾 Hike Description
We begin in the historic town of Lewes, a well-preserved Sussex market town dating back to the 6th century. After leaving the cobbled streets behind, our trail crosses the River Ouse and its broad valley, before climbing steadily into the sweeping chalk hills of the South Downs National Park. The early miles reward us with rolling hills, lush farmland and a sense of remoteness despite being so close to London.
From here, we push further into the Downs, following a succession of ridges and valleys that give this route its striking variety. The high ridgelines provide far-reaching views across the Sussex Weald and out towards the English Channel, while the descent into the dramatic glacial dry valleys reminds us of the land’s Ice Age past. These open, wind-exposed chalk uplands make for exhilarating hiking with a constant sense of big skies and changing horizons.
As the day unfolds, we finally meet the sea – and with it, the most iconic part of the hike: the Seven Sisters cliffs. This legendary series of undulating chalk cliffs rises and falls dramatically above the waves, providing one of the most photogenic and celebrated landscapes in southern England. However, today we don’t just admire them from afar – we take them on, cresting each hill in turn with unforgettable sea views to one side and rolling green downs to the other.
After tackling the Sisters, our hike concludes with a final push into the coastal town of Eastbourne. The route takes us past the Birling Gap Lighthouse, standing watch above the chalk cliffs and saved from coastal erosion by being moved 17 metres inland in 1999. From here, we continue along the undulating cliff path before descending into Eastbourne to finish by the beach. It’s a fitting end to a monumental day: 38km of hiking, nearly 1000m of ascent, and a true endurance test across Britain’s most spectacular coastal landscape.
