My husband and I are trying for baby number #2 now. I ran up until about 6 months during my last pregnancy but didn't have a routine. I just purchased a book on Amazon about running and pregnancy, that I'm excited to read. Do any of you marathon mommies have any advice about staying in shape while growing babies? My goal after baby #2 is to run a sub 1:40 half and then run the California International Marathon. I realize it takes 9 months for a baby to grow so you can't work the weight off overnight, yahta, yahta, yahta, but what can I do to be ahead of the curve?
