I’m not really sure what got me into biking. I was just naturally attracted to riding bikes from an early age and never stopped. As a teenager I also had a couple of close friends who were into road biking and we still regularly ride together 40+ years later!
Mountain biking came much later for me when I was in my mid 30s. I became good friends with a local bike shop owner and we rode the trails in a small shop group every weekend for several years before we eventually lost touch after our first daughter was born. I still ride mountain bikes now in my mid 50s, but do a lot more road biking.
I don’t think I will ever stop riding unless I am physically unable to do so.
