A special challenge for The Royal Marsden

Breathtaking route

Starting out in the perfectly preserved old town of Lewes our route will follow the stunningly scenic South Downs Way. We will be trekking over rolling hills, high ridges peppered with long barrows, ancient earthworks, and occasionally magnificent panoramas over the English Channel.

We will also tackle some fairly stiff climbs and descents. And eventually we will reach the breathtaking final stretch over the white chalk cliffs of the Seven Sisters, before finishing on the highest chalk sea cliff in England – the beautiful headland of Beachy Head. 

Challenge yourself

This is a surprisingly tough event over rolling Downs and cliffs. At 26 miles, it forms an enormous challenge for walkers. But it is so worth it.

There will be full support throughout the challenge with marshals and water stops along the route.
