South Coast Ultra Challenge 2026

Take on some of England’s finest scenery with the South Coast Ultra Challenge! - Starting in Eastbourne you'll head up to Beachy Head, over the magnificent Seven Sisters, and along the famous South Downs Way National Trail. There will be stunning views over the sea with Brighton at the mid-point. Then you'll continue to Devil's Dyke, welcome rest stops, a few ups and downs. All lie ahead before historic Arundel comes into view after an 100km amazing journey.

Whether you join as an individual or with a team, choose from 100km, 50km, 25km or 10km distance options, and either walk, jog or run for people living with cancer. 

Plus, receive a further 50% off Charity Sponsorship Places with Team Macmillan

All distance options have Charity, Mixed Funding or Self Fund options.

We'll provide you with a reason to keep going because you'll know that you're helping improve the lives of people living with cancer. 

Donations make up 98% of our annual income so we simply couldn't do what we do without you.
