The baby joggers are really good. We have the city mini which is not so much of a jogger one, but they are fantastic - really good build, fold small (and fold easily), very study, they have a large weight limit that's been tested so good if babe's possibly going to be big as he/she gets older.
I believe they all lie flat so can be used from birth. I know with the mini they also do a carry cot and you can get adapters to put a car seat on it so it's very adaptable.
I suspect the ones more suited for jogging are just the same sort of standard.
