I’m back at running after 20 years or so of not doing anything except riding my bike. And you know what? I am faster and I run longer than ever before. I’m not talking about when I was in high school and when I was able to run endlessly. Or, let’s just say, I am much better now than when I was years ago when I was overweight. Being skinnier helps me. But it’s not just that. It’s the energy. I just have much more now. Let me give you another example. When I was over 200 lbs I could barely move from my sofa after biking home from work. The daily biking beat the life out of me. Now I even take my wife for walks, play basketball with my son or even run 9 km in the evenings. In fact I walk 9 km to work in the morning and run twice a week. That is easily 60 km per week. The energy level increased so much.
