If something happened you'd never know if the over exertion was responsible.

I'd skip it. And I'm a hard core athlete.

Dumb advice. OP runs half marathons often. this is not excessive for her. For you, maybe...

I can tell you aren't in the health care field.

Op- I've done the MCM 7 times.

I never did it while pregnant.

It just wasn't worth the risk to me and too much conflicting info on it.

I did work out the entire 40 weeks with each pregnancy--including running--just not excessive mileage.

It's 10 months out of your life. Why risk anything?

I would ask my OB and also my running coach. Are you working with a coach or just an online plan?

OP here thanks! Ugh yeah does not seem like I should do it.

Here's an article with information from actual health experts, rather than anonymous internet posters: http://www.babycenter.com/0_running-during-pregnancy_7877.bc

It doesn't absolutely rule it out, but it does seem to present at least a slight risk. I would definitely check with your OB or other provider before doing it.

No, i wouldn't and i run and do triathlons. You would probably be fine but why risk it? The MCM will be there next year and the year after that and the year after that...

Personally I think I would be worried about whether my body could adequately supply enough oxygen to meet the baby's needs and mine under such duress. Surely your doctor has been consulted? Regular exercise is great but I'm not sure this qualifies.

Absolutely plan on doing it. Don't throw your prep out the window over a 2-inch fetus. Just be prepared to not feel up to it in some way. This pregnancy could go very differently from the first, in either direction.

12 weeks time frame is where I was most exhausted. I would fall asleep standing. Listen to your body.

I ran in 2008, and have done tons of 1/2 marathons since. Did my longest training run so far 2 weeks ago at 19 miles and did great. Feeling very conflicted. I am 36 if that matters, second pregnancy.

How has training gone so far? Have you run a marathon before?

Would you do it? Second child, planning on doing MCM and just found out I am pregnant!
