As a mom you're perfectly equipped to run. It starts with the birth of your child: an experience not unlike running a marathon. And as a child grows, many a mother has to do a sudden sprint to save him of her from a falling plant or something.
And just like running, motherhood requires perseverance. Of course, you cóuld stop midway, but then how are you ever going to get home? There's nothing for it: you might as wel continue. The same goes for mothering. Even though you sometimes feel like quitting, in the end you persevere. There's no turning back.
Running helps you find a balance in your motherhood. It's a time for you, and gives your a feeling of confidence and peace of mind. And hey, the fact that running has a streamlining effect on your body is a nice bonus. Sure you can eat that bag of chips! You'll run it right off.
