Again, Follow your doctors advise, but if you feel up to it give it a go. Give yourself permission to stop at anytime that it does not feel right to run, either walk or if you need to, stop the race there. Enjoy having a new running partner!! Speaking of which, do you have someone else (I was lucky enough to have my mom running a tri with me during my last pregnancy) that can help if you need it, just in case. Congratulations.

I ran St. George Marathon and did not know i was pregnant...very early. I did fine and ran normal (i'm a slow runner)... I miscarried my second pregnancy at 12 weeks and I know it was not because of running, but it was the most awful thing and I won't do anything to put my baby at risk... I'm pregnant again (due dec 13th) and I just make sure that I'm able to run and talk at the same time during my runs, (slower but still long distances 6-7 milers several times a week the first part of my pregnancy) as it got hotter (live in arizona) my friend and I just listened to our bodies (my running partner is pregnant too... so nice for us to have support from each other).. We never did less than 3 or 4 but have not yet gotten over 5 because of the heat (i will do up to 6 on the treadmill inside if my 2 yr old daughter lets me). Now here is my oppinion. The first part of my pregnancy was easy and i did fine running the same long distances that I was doing before... I've only run 4 marathons and I don't think I'd do a whole marathon knowing I was pregnant ever agian, however I'd do a half but very very slowly...no walking but walkers might pass me.... Keep working out during your pregnancy and get good weekly mileage (we do 20-30 a week which I think is good) and your delivery and recovery will be easier... then find a good marathon to run after the baby... you'll only need 3 or 4 months to train and you will loose your baby weight so fast... Get a baby jogger brand jogger as well.. they are the best!!!
