I first went on the road in a sidecar attached to my parents tandem at less than a year old. My father used to cycle the twenty five miles each way, to work in London by cycle (quickest method - and still is). My mother also used to commute ten miles or so to work by cycle. On Sundays we very frequently went out on a family ride with my sister.
We went on cycletouring holidays most summers as a family and my parents continued to do so long after me and my sister left home.
My mother not long ago at age seventy nine completed a veterans hundred mile run. She spent a few weeks touring France with a friend this summer. My father still cycles at eighty four but needs to be accompanied by my mother because he has trouble remembering where he is.
