Participants at the 20 anniversary KM Charity Walk this Sunday have the Maidstone Ramblers to thank for the stunning walking routes.

The organisation has planned the five-mile and 10-mile trails which both begin and end at Grade II listed Georgian mansion Mote House, Maidstone.

More than 400 walkers are expected to take part in the landmark event which starts at 10am and concludes with celebrations in the grounds of Mote House. Advance booking has now closed but participants are welcome to turn up and pay on the day.

Del Cook, chairman of the Maidstone Ramblers, said: “As members of Britain’s leading charity campaigning for the preservation and expansion of our fantastic national network of public rights of way, we are delighted to be working with the KM Charity Team to promote the value of regular walking as a foundation for good health - and of course to play an active role in an annual event that raises so much money for so many good causes.”

Walkers will earn stamps at stamping stations along the routes in return for goody bags and souvenir medals at the finish line. Participants are invited to stay on and celebrate their achievement at the KM Charity Walk summer garden party featuring barbeque, drinks and a string quartet.

Prizes are up for grabs for participants wearing the best yellow or gold outfits in keeping with the special 20 anniversary theme.

Tickets cost £15 per adult, £2 per child or £30 for a family pass of two adults and up to two children.

Check in for the 10-mile walk starts from 10am and 11am for the five-mile route.
