Rode my 1st racing bike, a neighbor's pre-WWII track bike during the Johnson administration, joined a cycling club 51 seasons ago.
I don't count riding a bike as a kid "cycling", but it was an essential part of growing up and great preparation for getting into the Sport.
Still ride on the road, no more MTB, and continue w/ what is essentially the same seasonal "program" for decades re-tuned for reality as required, so far so good....
