The South Downs National Park is a superb backdrop for 2000 adventurers to take on a real challenge, and you can take it on at your pace as a walk, jog, or run – and fundraise for our life-saving work.
An Eastbourne start, up Beachy Head, the magnificent Seven Sisters, and along the South Downs Way, with stunning views over the sea, to a Brighton half-way. Devil’s Dyke, and a few ups and downs lie ahead before Arundel comes into view after an amazing 100km journey.
Sign up as an individual or as a team - you’ll get full support all the way, plenty of food and drink, optional camping and transfers, a special medal, t-shirt and celebration finish. With half and quarter distance options also available – there’s a challenge for everyone. Push yourself further in 2026, take on an Ultra Challenge – the UK’s No.1 Series of treks and trail challenges!
