A challenge event you can take on at your pace. The North Downs 50 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 Sense.

Join us in the North Downs with a fabulous challenge setting out from a Guildford basecamp. Take in some of the best of the Surrey hills, the North Downs Way, and the surrounding countryside. A route with real variety and some wonderful scenery & views – and easily accessible from London – there’s a North Downs 50 Challenge for everyone! It will test spirit & determination but is totally achievable with good preparation and the Ultra Challenge support. With 50km, 25km and 10km challenge options 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.
