This is the end of season Ultra Challenge – in the ‘Garden of England’ – with a basecamp near Maidstone, parking & weekend camping options. The main 50km looped route heads anticlockwise around the Kent Downs – starting on the North Downs Way to Blue Bell Hill, around picturesque Aylesford, and following the River Medway to Mote Park at halfway for a picnic. Along the Len Valley Walk to the majestic Leeds Castle, then the North Downs Way back to the showground finish line and celebration. It will test spirit & determination but is totally achievable with good preparation and the Ultra Challenge support. 

With 25km and 10km 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.
