Whenever I try to go for a decent run, it's usually my breath that I lose first... either by a kind of cramp or lack of said breath.
What can I do to get my breath up to par with my legs?

Build cardio.

Keep running, and don't smoke.

Don't smoke, don't inhale second hand smoke.

Check with your doctor for any kind of lung problems e.g. asthma etc..

Also do what you can then gradually step it up.

Increase lung capacity by doing breathing excercises. Take deep breaths while running instead of short ones and breath in through the nose and out through the mouth.

suppose you could also do cardio at a higher elevation, that way you're lungs won't need as much oxygen once you get back to whatever elevation you live at.

Oh, yeah, sure I think Master will walk out of him home, take a air plane, take a bus, and take a heli out to mount everest just to get higher elevation.

While you are on the streets, you won't get higher elevations lol.

For the record ... you're doing cardio. Your cardiovascular system SHOULD be the thing that gives out first, not your muscles.

I don't see a problem.

I don't smoke kthx.

I'm totally gonna try that.

Guess I should be more specific; I want my 'cardiovascular system' to last longer, allowing me to cover more distance with the remaining muscular energy I have.
I was thinking slow but long jogs to start?
