There is no concrete answer to this. As I've previously posted, I've been running since I was young so it has always been a part of my life. I go through periods where I absolutely LOVE running. I just have the desire to bust out of my office space and run down the street. When I feel this way I can't get enough, running clears my mind and energizes my life.
I would be lying if I said that I always felt this way about running. Sometimes (like for the past couple of weeks) I just don't feel like running. I don't know why but I go through these periods where I just don't have the desire to run.
I think it all comes down to why you are running. I have lots of friends that run and they have a variety of reasons as to why they run (companionship, health reasons, sanity, etc.) I think that if you stick with it for a while you will start to love it. And if you don't love it then don't do it. I am a big advocate of running and I think everyone that can should do at least some running but life is too precious to waste time on doing something you REALLY don't enjoy.
There is always cycling....
So fellow runners; do you have any advice for Sian? When you started running did you automatically love it or did it have to grow on you? If so, how long did it take?
