I don't keep track of my miles any more. I glance at my computer after each ride, but I don't record my mileage and I enjoy riding more than ever. I have been cycling for 25 years and didn't for 5 years routinely and became very fat.
Started riding again and rode myself into shape (260lb to 180s). All I know is I ride a lot and am getting stronger and stronger. I used to be more obsessed with my mileage and times, but had an epiphany last year and I ride for the sake of riding and not the stats. The more I am enjoying my rides, I am riding longer and farther than ever in my life.
