Just did
Started riding "seriously" around 12 years old. I tried it all, racing, tons of day rides, and went on an overnighters with the bike club. All was great but nothing hooked me. Then when I was 15 I did a 1000 mile 24-day tour with a teacher in the bike club doing a combo of riding RAGBRAI riding via Minneapolis to ride SAAGBRAW (the original newspaper sponsored one) via Minneapolis. Got hooked.
During my high school junior summer (before senior), I did the TransAm by myself. Been touring for almost 40 years now. Tailwinds, John
