When I lived in Belgium, we saw the prologue in Charleroi, and picked up other stages in 1975...Eddy was still wining back in those days and Van Impe was the perennial King of the Mountains...then a fan ran into the road and punched Eddy in the abdomen brusing his liver and he was never the same rider.
Living in Belgium and seeing bike racing...if you are a fan of the sport you need to see one or two classics...
