Can any one recommend a pushchair that goes off road? I don't mean just over grass, I'm talking bumpy woodland tracks, moorland and up/down smaller hills. I've been looking at the baby jogger summit x3 but there doesn't seem to be any off road reviews online. It won't be my main pushchair, I have another for shopping and family days out etc. I'd be using it for dog walking but I live in a very rural area with no paths or parks. Also needs to be suitable for a newborn. Thanks for your help.
