Pre-Training: running is not for weight loss

In reading about marathons, we often hear of the runner losing several pounds during the race. This is water. In actuality, less than a pound of fat energy is needed for a marathon. Typically most runners don't burn fat at the beginning of the race. They're using their glycogen stores for energy and those stores are replenished by carbohydrates. I'm going to have to increase my calorie intake and ensure that carbs are a large source of those extra calories.

In short, running is not really a weight-loss program, though many think it is. If you run more, your appetite increases and you eat more. The extra eating and the switch from fat to muscle in your body means you will be more fit, but you may not lose weight. In fact, my weight loss slowed considerably when I started running due to my bulking up.

Today's run seemed hellish. Again, it was only 3 miles, but my body was not into it. I had to stop twice -- once at a busy intersection and once to tie my shoe -- but both times had me stopped for 10 seconds or less. Other than that, I ran the whole way. Out of curiosity, I didn't try to pace myself today. I deliberately ran at a comfortable pace and did my first mile in under nine minutes. However, it still took me 30 minutes to finish the three miles as I slowed down considerably towards the end. I'm glad tomorrow is a day off from running.
