Some riders are all about speed and riding lot of miles. Others could care less about one or the other or both. I have noticed that the older I get the less I care about the speed or distance I ride. For me I am more concerned about how long I am out riding than I am about how fast I am riding or how far I ride.Knowing I am out riding pretty steadily for 4 +/- hours is more important to me. I know I got X number of minutes of exercise that day. A few years ago I rode more miles in a day than I usually do now. I didn’t necessarily ride faster but I think I usually rode longer. Obviously riding faster over the same time frame will result in more distance. I see some bicyclists flying by me and get the same mileage in I get but in a fraction of the time. They quit upon riding a certain distance I am still out there riding long after they are done. They might be getting healthier exercise, but I really don’t care. I am just out to enjoy riding. For me to try to ride faster or further than I do would turn it into something I would not enjoy nearly as much as I do now.
