Pictured with Duncan Fitchett and Phil Sharp. Always used to bring me biscuits and cake from whichever B&B they were staying at. A real gentleman, he used to tell us about their engineering business. They always had kind words for the marshals and time to chat. They were generous to their sponsored riders and the club.
