There is no need to book, just bring suitable footwear and clothing for a short walk in the woods and don't be late.
A recently established Coventry Sherbourne tradition is blowing away the cobwebs on Ollie (Copeland) the dog's Boxing Day Walk, which takes place er... the day after Christmas Day. Meet at the far end of Birchwood Road, Binley Woods. When driving from Coventry, turn right opposite The Roseycombe and keep going, before parking (considerately) near the far end of the road.
