Long Distance Runs During Pregnancy

by Christine
(Philadelphia, PA)

I run about 100 miles per week right now and have been running in marathons for over a decade. I am pregnant now and I am wondering if any running moms out there continued to do long distance (about 20 mile) runs within their daily running program? I realize my pace will slow and I will not be able to run as much as my pregnancy moves on, but I would like to keep at least one long run per week.

I would appreciate if you could share your experiences regarding: baby health/complications with long run, dehydration prevention, bathroom breaks, and how long into your pregnancy could you do these long runs?

50k pregnant?? NEW
by: Anonymous

I ran during my first pregnancy but the longest was 10-13. I just found out I'm pregnant again and I've been training to run a 50k next week I'll only be just over 6 weeks. I don't have a doctor appointment till next month so won't get to talk to them about this. Just wondering if anyone ran that far pregnant and how safe it is? The 50k is a 5 mile loop that I'll get to stop and eat and rest if needed. I'm running with a group of friends that I've been training with and was not planning on telling them I'm pregnant so I'm a little worried if I can even get out of if.

12 weeks pregnant and still running NEW
by: Mary T

I am pregnant with my first child and I have continued to run and run long distances. I have been ultra running for the past year and plan to continue that until my body says "no!" I have run two marathons and a 50K trail race within the first 5 weeks of pregnancy. I have another trail marathon coming up where I will be about 14 weeks pregnant. I have continued to run my weekend long runs 10-15 miles Saturday and 15-25 on Sundays. I scale back on the 20 milers every other week just to avoid injury. When on my long runs I take my hyrdation pack to ensure I am drinking plenty and have food/fuel on me so I don't let myself get hungry. I may urinate more often but I know my baby is okay if I do that. I have also found that along with the prenatal vitamin, I take an iron, potassium, and calcium/magn/zinc supplement a few days a week. (specifically I take these a few days before I know I am running long over the weekend) I don't currently show but I am a little worried about other people's opinion when I am showing and I am still keeping up the miles. I know my body better than anyone. One thing I have learned from ultra running in general is that I have to listen to my body. I feel like I am very intune. I don't want to fall victim to irresponsibility and end up in the hospital after a race or long training run. So running pregnant, I know come 5-6 months my running will definatley decrease. However up to that point I plan to continue at the level I am comfortable. I know I can continue to run as long as I listen to my body. If I need to walk so be it, if I need to slow down and run with slower people, so be it. If I start a race and need to DNF, okay... no big deal. My boyfriend runs too and when I am further along in my pregnancy I will get the pleasure of participating as a crew member for his runs and supporting him and my other ultra runner friends.

I ran about 50 miles a week while pregnant. I even ran a marathon with baby #3. I did slow down and I didn't run as much (normal mileage is 60-70 miles/wk).

What I did was run for time instead of distance. I never wanted to harm by baby and exercise will NOT do that but I was worried about others opinion (probably too much). Just listen to your body. It will tell you when to stop. I ran up until the day of (or the day before for my 4am baby) I delivered. I only gained 20lbs with each and was back at pp weight before my 6 week check-up. I ran a marathon 5.5 months after the 1st, 4 months after the 2nd and 11 weeks after the 3rd.

Hope that helps!
