congratulations, Becky! how exciting for you. most women can continue their current level of exercise while they're pregnant. that means, if you're currently riding a certain duration you can most likely continue to do so.

there are some common exercise restrictions during pregnancy, but your doctor should be able to explain them to you. for example, it's contraindicated to exercise on your back after the first trimester. it's also typically recommended that you don't let your heart rate exceed 140 after the first trimester. but again, your doc should be able to give you solid guidelines.

since you're in the bay area, check the velogirls yahoo group archives. I know many members who've become pregnant and there have been many discussions on the list of this topic.

personally, I know women who have continued to ride and race (yes, race) right through their pregnancy. of course, your results may vary.

again, congratulations!
