John is a regular contributor to policy development, a frequent attendee at Scottish Parliament committees and is often sought as a commentator in the Scottish media.

John was born in Coldstream, Berwickshire in the Scottish Borders where the walking and cycling habit took hold. After working in school, academic and national libraries he took a change of career and joined Sustrans Scotland.
