Amber Miller had already run one marathon during her pregnancy and wasn’t about to let contractions stop her from finishing her second. Shortly after completing the 26 miles of Chicago’s Marathon (in six and a half hours), Miller gave birth to her second child. Amazing, yes, but was it dangerous? The web is buzzing with speculation over whether her physical feat might have been dangerous—not just for her but for her baby. According to the American College of Obstetricians and Gynecologists, athletes can continue with their typical routines under a doctor's supervision, leaving commentators to admit that Miller might just be a supermom.
