I think the same logic applies to reading about running and pregnancy: everyone has an opinion, and everyone wants to share their experience. But each pregnancy is different, each woman is different--as a mom, as an athlete. The most important thing is to get your doctor's approval and guidance. Ask as many questions as you want, and then, within their recommendations, do what you are comfortable with.
Some of the articles I read made me wonder whether I could have run much harder during my pregnancy. And some articles and comments I read made me question running at all. Was I selfish to run? Was I lazy for cutting my mileage so much?
I had to take a step back and remind myself of two things:
1) My doctor fully supported my running. The only limit she set was to listen to my body and don't overdo it.
2) I know how to listen to my body. I know when I'm overdoing it.
Angst aside, I still love to read about running during pregnancy--personal experiences and research alike. Below are
