The Great British Dog Walk

Get a breath of fresh air in the grounds of the National Trust's Osterley House at this charity walk in aid of Hearing Dogs for Deaf People. Countdown's Rachel Riley will be joining in the fun, and participants can choose a 3km or 8km route. Dogs are welcome (but not obligatory), there'll be puppies to meet and the Hearing Dogs display team will give demonstrations. Book your place in advance on the Great British Dog Walk website.
