Smoked for most of my adult life. Rag on me if you wish, I deserve it. About 4 yrs ago finally saw the light. Asked my PCP for Chantix Rx. Knowing I had only about six weeks to affect a lifestyle change, chose cycling. Bought a Specialized Expedition, which I really liked, but eventually felt should have been one size larger. I seem to recall my first rides were 6-8 miles. Early this year suspected I preferred a more aggressive riding position but not a true road bike because I like to venture off pavement sometimes. I settled on what they call a gravel bike, road bike with 40mm tires in my view. Anyway, now doing 15-25 miles several times per week. My longest so far is 42 mi. last year and rode the Kal-Haven Trail a week or so ago. A minor achievement to most, but on my bucket list.
