Dear Fitness Expert,
I have been training for the NYC marathon and have completed two marathon's in the past 10 months. I am not a competitive runner, but enjoy marathon running and finished both marathon's in just under 5 hours. I just found out that I am pregnant and will be 6 weeks pregnant during the upcoming run. Both my primary care and OB/GYN had no objections. Both also advised that I be careful not to dehydrate.
