Running During Pregnancy

What’s the first thing you do when you find out your pregnant and you are a runner? Google any and all information on the topic?

You may find that there really isn’t much out there in the way of what the nitty gritty is like while running pregnant. There is the usual recommendation – you can keep running if you ran before you were pregnant, if you didn’t, now is not the time to start. But beyond what the Dr. says, what’s it really like to run with another human growing in your body?

I am here to help you with any questions you may have on how to run before, during and after childbirth!

I have successfully run through all three of my pregnancies. Each pregnancy presented it’s own unique challenges while running.

After the birth of my first baby I began running shortly after and ran my first 10K 7 weeks postpartum. I began training for a marathon when she was 9 months old. Shortly before her first birthday I found out I was pregnant again with baby #2 and put my marathon training on hold till after he was born. I firmly believe in running while pregnant but DO NOT agree with running marathons.

After the birth of my second child my body was able to recover quickly and get back in to training. I credit this to entering this pregnancy in the best shape of my life. 6 months after he was born I ran a 24 minute PR in the marathon and qualified for Boston for the first time with a time of 3:36. In the years following the birth of my 2nd baby I took my marathon time from a 3:59 to a 3:21.

I again entered into my third pregnancy in what I would consider the best shape of my life. At 25 weeks I completed 10 miles non-stop running. My last pregnant run was 3 miles non-stop 3 days before he was born. My first run back was 8 days later, 1 treadmill mile. At less than 8 weeks postpartum I completed 2 – 10 milers, 1 – 12 miler and a timed mile on 12/31/10 in 6:42. 4 months after he was born I ran my 2nd fastest marathon time of 3:26. I followed that race up with Boston Marathon in 3:30 and then Potomac River Run Marathon in 3:23. 3 marathons in 5 weeks achieving my 2nd, 3rd, and 4th fastest marathon times. My marathon PR dropped yet again and I am down to 3:11.

I am firm believer in the faster after kids notion – I train harder and more effectively knowing my options to get out there are now limited.

I now train weekly with all three of my children – pushing them in a single, double or triple stroller.

Below you will find information I have compiled from the Internet for quick reference.

Congrats on entering a new stage of your running life!


  1. I also ran during my ENTIRE pregnancy (my last run was at 39.75 weeks the day before I gave birth, 6 miles). Now I am 5 weeks postpartum and am incredibly interested in finding information on running AFTER baby. My hips hurt like crazy and I’m having trouble getting back into it. Yes, I know, I’m only 5 weeks postpartum but looking for information nonetheless 🙂

  2. I am 15 weeks pregnant and a former runner. I did a half marathon when I was in college (about 8 years ago) and loved the experience of training and the discipline of regular workouts. I have run off and on since then, but I have not trained regularly. I just finished a very intensive graduate program and did not run at all during that time (though I maintained a moderate level of fitness by walking around campus about 2-3 miles per day). I was hoping to start training for a half or full marathon when I found out I was pregnant. For the first trimester I couldn’t even think about running. I barely had energy to walk and do yoga, but when I did it always made me feel so much better.

    Now that I am entering the second trimester I have a lot more energy and I would love to have a regular training plan that includes running. However, I don’t want to start out at too high an intensity when I’m not already in shape. Do you have suggestions to monitor intensity? How do you know if you’re getting too out of breath? Do you have any suggestions of books or other resources that might be helpful?

  3. I am a firm believer in running and exercise during pregnancy too granted there are no complications. I ran through all 3 of my pregnancies. With my daughter to 38 weeks which was the day I went into labor. I am almost 6 weeks pp after twins currently and started back running at 2 weeks. My doctor gave me the okay to run until 35 weeks with twins. After that I stopped and they were born at 38.5 weeks. Being in good shape before pregnancy really helped me a lot.
