I didn't have a bike as a child, but when I spent four weeks at a school camp at the end of my last year of primary school, I managed to pass my Cycling Proficiency Test, and was awarded - yes, you've guessed, a certificate
these photos show me from just before starting school (top left), then clockwise through primary school, ending with my first year at the Academy. The triangular badge on my lapel is my Cycling Proficiency badge, worn with great pride!
