About the event

Push yourself to the limit on this unique night time trek through the South Downs National Park. Following part of the famous South Downs Way, you’ll battle fatigue, the elements and the demanding terrain of one of southern England’s newest national parks. You’ll negotiate the rolling chalk hills and cliff tops that lie between Firle Beacon and Beachy Head.

Walking until morning, you’ll cover a marathon distance of 42km, including the famous white cliffs of the Seven Sisters, before ending your gruelling hike on top of England’s highest chalk cliffs. In 2016 the National Park was granted International Dark Sky Reserve status, making it one of the best places in the country to view the night sky. As dawn breaks, your hard work will be rewarded with breath-taking views across the South Downs.
