LOVE MY BOB!!!! I bought the bob as the very first baby purchase 2 days after I found out I was prego (it went on sale, so good timing).  It was one of the most expensive baby items I bought- but well worth it.  I run 3-6 times a week, and while I was on maternity leave my baby came with me nearly every day.  I got the infant car seat adapter which was a pain to put on the Bob, but I love that I can just click her car seat right in & attach the safety strap & that helps absorb some shock & keep her super safe.  Pushing a stroller while running is a little hard on my back, but I suspect any...
