About London 2 Brighton Challenge

A challenge event you can take on at your pace. The London 2 Brighton Challenge invites you to walk, jog or run a distance of your choice, along a signed route, with free food and drink at regular rest stops, plus support including medics, marshals and massage. Get the ‘Ultra Challenge’ support & hospitality all the way – helping you to push yourself further and achieve something really special for Cancer Research UK.

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. As Cancer Research UK are an official partner on this event, you get a 50% discount on the ‘Full Sponsorship’ registration fee when signing up to support us.

Why take part with Cancer Research UK?

Meet Rika

My favourite moment was the Cancer Research UK cheer point, where my beautiful daughter and incredible husband were cheering me on!

- Rika

Rika joined Team Cancer Research UK in 2025, running in memory of her Mum.

"I relied on Cancer Research UK to learn more about breast cancer when my mum was diagnosed. Educating myself was a productive way to try and process everything. I eventually lost my mum to breast cancer in March 2020. It was a no brainer when it came to choosing a charity to raise money for. My mum was a gym bunny, so I thought she’d find it funny that I was going to be running in her memory. I enjoyed every single mile."
