On October 9th, at 38 weeks gestation, a pregnant woman completed the Chicago marathon—all 26.2 miles. She reportedly ran a bit, walked a bit. Seven hours later, she delivered her newborn. The infant reportedly was 7 pounds, 13 ounces and appeared to be doing well.

With news of this self-described "marathon mom," many took to Facebook, Twitter and other sites to voice their approval: "She is fantastic!" "Awesome!" "Woman power!"

Others voiced their disapproval: "How selfish." "What a risk to her baby!" "Couldn't that have waited?"

The American College of Obstetricians & Gynecologists doesn't have a specific guideline about women late in the third trimester running full marathons, although ACOG does allow that pregnant women exercise with their doctor's approval. That approval comes after the doctor has taken a full exam and knows the woman's medical history and past pregnancy outcomes to advise her of risks.
