One of my favorite cycling goals is to ride as many miles as I am old on my birthday. So, for example, when I turned 65, I did a 65-mile ride. I’ve done this birthday ride many times, sometimes alone, often with friends, and I find that the day is always an affirmation of life: I’m still here and mobile! But sometimes life throws you a curve, and your goals need major modification. That was the case for me on my 66th birthday, when, instead of riding 66 miles, my goal became walking 66 steps. The reason for this much more limited goal was simple: I had quadruple heart-bypass surgery the day before.
