Is It Safe For Baby?
Your question 
I'm training to run a half marathon and planning to get pregnant. Can I still run a half marathon if I just find out that I am pregnant? - Carol, Miami
The expert answers
Carol,
The first thing you need to do is talk with your caregiver about your pregnancy and running plans. Many women continue to run safely throughout their pregnancies, so unless you're at risk for preterm labor or another related complication, I don't expect that your caregiver would have a problem, especially since you're already in training.
That said, please realize that you may feel unusually tired and/or nauseous in your first trimester of pregnancy, so you may need to cut back on your training schedule. Many competitive female athletes tend to overlook their body's signals for when to slow down, especially during pregnancy.
Remember: Your main goal is to grow a healthy baby, so don't ignore your body's efforts at helping you reach that goal!
