Running too slowly is jarring (aka jogging). Running at the proper stride for your height should be fairly smooth and not hard on your knees/shins etc.
Walk, run, or sprint but don't jog.
Hill runs are great for building the calves. The downhill part can be very jarring on the knees though if you don't control your pace.
I can run a 10K with no shin splints. I can "fake" run beside my 4 year old son (while he runs) using choppy, short strides and my shins will hurt within seconds.
