Kent Downs 50 Ultra Challenge

Take on the Kent Downs 50 Ultra Challenge and get ready for a spectacular end of season event in the ‘Garden of England’. Join over 1,500 Challengers walking, jogging, and running across the Kent Downs, whilst fundraising for charity and making a real difference.

Head out from basecamp near Maidstone on an anticlockwise journey across the North Downs Way. Walk, jog, or run past Blue Bell Hill, then follow the River Medway to Mote Park at the halfway mark for a rest & relax with a picnic. It’s then along the Len Valley Walk to the majestic Leeds Castle, and back on the North Downs Way back to the showground finish line.

Join as an individual or as a team and get ready to experience full support every step of the way. Regular Rest Stops packed with food & drink, hot meals, fully marked routes, massage & medical care, marshals on course and walking the route with you, and of course an unbeatable community. There are even camping & transfer options available so you can plan your whole weekend smoothly.

Join the UK’s #1 Series of treks & trail runs in 2027, and push yourself further with the Kent Downs 50 Ultra Challenge.

All distance options have Charity and Self Fund options.
