Keep in mind that you cannot jog with an infant under at LEAST six months old. THe BOB series stroller is great because of the wheel thing however it lacks in support for the baby which is more important of course. There is a cushion called the kiddopatumus (sp?) available at all baby stores and they are a fantastic cradling cusion to put in your baby's stroller for support for the first few months. My kids loved cosying up in theirs and inventaully my chihuahua inherited it!

Congratulations on your baby to be...my experieince with running with my baby has been the best thing is to have someone watch the baby while I go run...and I was very determined to run with my baby but it just was too **** hard with the cars and people not moving out of the way and the baby getting fussy. I never really had a "good" run and was usually aggravated when I got back - but everyone is different. My daughter is four now and she wants to run with me now side by side HOW COOL IS THAT

Ihave the Baby Jogger II from 12 years age and the Baby Jogger III and I love them both - There is a new version that has some nicer features like a better sun shade. My husband and I push each one of our boys on a very hill terain with little difficulty.
The down side is the stroller doesn't fold as easy as others( The city edition does fold better than the performace edition.) and it is wide so it is cumbersome to put into a small cars trunk.
Also there is a car seat attachment bar available if you want to use it for walks when the baby is small.
