Got into cycling when I was about 36. In my youth I was taken up with football and baseball. Went to college on a football scholarship. At age 36 my first ride was a Century. Seriously. Got talked into it by my bro-in-law who had just run the Boston Marathon. One of us was in shape. I knew nothing about cycling. Thus the stupidity. At the end I couldn't walk for 3 days. Literally. Decided I had a choice...put the bike away forever or learn about cycling. I have no idea why but I ended up cycling. It has now been 37 years on the bike. And, at age 73 I am stronger, faster and happier than I've been in many years.
