Join 2,000 adventurers of all experience levels & ages and take on a classic capital to coast route. Test your grit over the Bank Holiday weekend. A Richmond start in Old Deer Park - then the North Downs and wonderful Surrey & Sussex countryside to halfway at Turners Hill. The full challenge heads up and over the South Downs before the welcome sight of the Brighton coastline comes in to view. It’s a test of spirit & determination but is totally achievable with good preparation and the Ultra Challenge support. With 75km, 50km, and 25km challenge options also available - there's a challenge here for everyone – and you can join as an individual or as a team of friends / family.
You may have to dig deep at times, you’ll meet new friends along the way, and the journey will be unforgettable! As you cross the finish line, you’ll get a big welcome from the cheer squad, a glass of fizz, t-shirt, and a special medal to celebrate your achievement.
