Countdown star Rachel Riley accompanied more than 300 dog owners and their pets for the Great British Dog Walk at Windsor Great Park.

Their aim? To help raise money for the charity Hearing Dogs for Deaf People.

Rachel officially started the walk on Saturday, April 29 with a unique ‘countdown’ to send the party of pooches and their owners on their way.

The sold-out event is one of 20 around the country and a flagship walk for the national charity, which changes the lives of many people in the UK by pairing them with dogs to assist with every day challenges.

The charity celebrates its 35th year in 2017.

The maths whizz also took the lead of hearing dog Tilly and met owners, volunteers and fundraisers.

Rachel said: "I hope we raised lots of money for Hearing Dogs so this amazing charity can train lots more clever, loveable pups to support deaf people. I wish I had a dog like Tilly to wake me up every morning, it really was a pleasure to spend time with her.”

A 9km and 4km route through the beautiful park, made it an ideal event for dogs of all shapes and sizes, families, couples, independent walkers and organised walking groups.

Southern Counties Community Fundraising Manager, Nicholas Orpin, says: “We had a great turn out from a fantastic group of people who are passionate about the charity. Anyone can go for a walk in Great Windsor Park, but the people who joined us chose to come and make a donation to Hearing Dogs for Deaf People, helping us continue to do the amazing work we do.”
