Choose a Well-lit Route
It might not be your favorite route to run, but the most well-lit route is your safest choice. Oncoming cars see you better, and you'll always be able to see the road and avoid potential hazards.
Always Run Against TrafficIt's easier to avoid cars if you can see them coming. Avoid busy roads and those with no shoulders or sidewalks.
Be VisibleIf you're running in the early morning or at night, even at dusk, wear white, yellow, or orange clothes. Also, make sure you have reflective gear on. Although some items (running shoes, jackets) already have reflective pieces on them, it doesn't hurt to add more. A headlamp is also a great item for runners who do a lot of early morning or evening runs.
Always Have Identification on You
Put your driver's license in your pocket or wear an ID tag on your shoe.
Vary Your Routes and TimesPotential attackers can study runners' routines and loom in a particularly dark or isolated area. Don't make yourself an easy target.

Watch out for bikes and runners.Even if you're running on a path or in a park with no cars, always be aware of other runners and cyclists. Before you stop or turn around, make sure your path is clear. This advice applies to running in both daylight and darkness.
Ditch your music.Make sure you leave your radio, MP3 player, or iPod at home. Cutting off your sense of hearing leaves you at a disadvantage. You can't hear oncoming cars, cyclists yelling to move, dogs, or any other potential threat.
