One thing I'm enjoying about Couch to 5k is that it insists on a five minute walk before I start running. I enjoy walking, especially in this sunny weather.
I read the other day that running a mile burns the same number of calories as walking a mile. In other words, I could get the same results without half killing myself. In even more other words, what's the point of trying to run 5km when I can already walk it?
Well, here are the answers:
- Time. I can run a mile in ten minutes, but it takes me twenty minutes to walk it. In other words, I burn those calories in less time. When I run back from the morning school run I get home with a good five minutes to relax before I am due to start work (I work from home, 9-2). When I walk back I often open the front door to the sound of the office phone ringing. I'm usually pretty short on time, so being able to run buys me more.
- Afterburn. Running raises the heartrate considerably, and that can burn an additional fifty or more calories in the half-hour after my run is over. I don't get that with walking.
- It might not be true anyway. More recent research suggests that, in fact, running burns around 26% more calories for the same distance as walking. Studies are ongoing, so I shouldn't throw in the running towel just because the urban myth is that it doesn't make a difference which I choose.
- I may claim to be running just for weight loss, but in fact the underlying reason I want to lose weight is because I want to be healthy. I want to lose weight so that I reduce my risk of heart attack, stoke and diabetes, so that I can be active without getting out of breath and so that I can improve my asthma and my general quality of life. Well, running gets me to those goals too. I am not running for weight loss, I am running and losing weight in order to be healthy.
