2,000 adventurers of all experience levels & ages will take on a classic capital to coast route, testing their grit over the Bank Holiday weekend.

Most will walk, but many will Jog or Run the full 100km. And with half & quarter distance options there's a challenge for everyone. A Richmond start by the Thames-then the North Downs and wonderful Surrey & Sussex countryside to halfway at Turners Hill. The 100km route heads up and over the South Downs before the welcome sight of the Brighton coastline comes in to view. Your entry includes free food and drink at regular rest stops, plus support including medics, marshals and massage. As you cross the finish line, you'll get a glass of fizz, t-shirt, and a medal to commemorate your achievement.
