Although your activity level sounds appropriate for a JRT, there are a lot of other considerations to make:
Do you have any other pets, or children (or plan on either in the future)? JRTs aren't know for being good with either other animals or young kids.
Do you plan on taking the dog to a dog park for exercise? Most JRTs can't handle a dog park.
Do you have a lot of experience training and raising dogs, particularly terriers? JRTs can be a challenge to train and are typically recommended only to experienced owners.
Are you prepared, living in an apartment, to deal with reactivity? They aren't know to be horrendous barkers, but some are, they'll often bark at windows, other dogs, or just general apartment noises, and can have tendencies towards chasing cars/bikes/wheels or reacting to other dogs on leash. It's not impossible to handle with a small dog, but can be more inconvenient than many people are looking for.
I would recommend going to a breed show or a flyball event and talking to owners in your area about their experience. If you do pursue a JRT, I'd recommend an adult dog (either rescue or rehome) so you have an idea of how the dog will be at maturity with city life.
Other breeds you might consider are a Chinese crested or poodle, both of which are smart, good apartment dogs, and excel in sports.
