Shit knees are from weak legs faggito. Distance running is fine if you warm up, have dynamic all around leg strength, and don't weight 300 lbs.
Exercise the top of your feet, shins, quads and hip flexors to run without issue. Sprints definitely go a long way in upping leg strength, but don't be a faggot who blames flat concrete jungles and a lazy foot strike for shitty knees. If you run like a lazy mexicano, you will have a lazy degenerative knee. Run high knees, low contact time, forefoot strike, when running distance to simulate the form of sprints and correct lazy running form with high-effort running form. Engage your core and swing your arms with vigor as well.
After you're done, don't go plop somewhere, do something else vigorous or with vigor. I don't care if you're reading a book, do it with vigor and virility. Try harder, don't be lazy.
