Jogging stroller for 2?

FTM and runner/athletic... I’d like to get a jogging stroller that is capable of attaching an infant car seat. And if I may be so greedy- I’d also like a stroller that would convert to a double if we are lucky enough to have two children. (Will be trying to have them close in age due to my age).

Anyone have any recommendations? Advice?

The stroller travel systems are complicated enough let alone trying to find one that is a jogger and possibly fit two. I hate spending money on one only to turn around and maybe having to buy a double in a less than two years since they are so expensive .
