At the beginning of the year I was very unfit and horribly overweight. I started to walk to work and back every day. At first the 3.25km walk took me almost an hour. I then got the walk down to 40 minutes and started to feel fitter and leaner. I then started to dream about being able to run. The dreams were brilliant. I felt so powerful and strong and exhilarated. I really wanted to run but didn't think I could. But then I just couldn't help myself and started to run a bit then walk a bit. Now, three/four times a week I run to work every morning and back again in the evening without stopping. Sometimes I extend my run on the way home as I am 2 stone lighter and I really do feel powerful and strong and exhilarated when I run. Is it okay to run in the morning and in the evening? I worry in case I am not allowing my body enough time to recover during runs. I have proper trainers now and my knees are grateful for them.
