As a parent, would you allow a 15 year old girl to go on a jog by herself?

im 15 and im in track. its off season now and i really want to go out running on the sidewalks and stuff, but my parents won't let me. im turing 16 in 2 months. how can i convince them to let me go on a couple miles jog. im not going through the woods or anything, im on a local road- sidewalk. thanks!
