Though people like to think they live in an enlightened time when women are safe running by themselves, it's always a good idea to be aware of potentially unpleasant or dangerous situations. Here are common-sense suggestions to keep you safe. These tips also apply to men.

• Don't run in isolated areas, particularly after dark.

• Whenever possible, run with other people after dark.

• Vary your running routine. Don't run in the same place at the same time on the same days.

• Mix up your schedule so strangers can't anticipate when and where you run.

• Tell a family member, roommate, or friend of your route and approximately what time you expect to return.

• Bring a whistle, panic button device, or some other way to attract attention should a threat materialize.

• If possible, learn some self-defense tactics.
