When I asked yesterday if the dark mornings were making it difficult to work out before work, a few of you mentioned safety issues about running in the dark. I agree with this challenge as I try to fit my runs into days with fewer hours of light. If you can't rearrange your schedule to move your workouts to a brighter time of day, you want to make sure you can be seen by cars, bikers, and fellow pedestrians. Wear light-colored clothes, preferably ones that contain reflector strips. If it's really dark out, a blinking LED vest ($35) will allow you to be seen up to a mile away. If that's a little too much for you, attach this Petzl Safety Light ($15) to your jacket or these Cat Eye front and rear lights ($30) to your bike. Once you have your safety gear on, you'll feel good about working out in the dark.

Fit's Tips: For added safety, find a buddy to run or ride with you. But do remember, just because you are wearing lights and reflectors doesn't insure that you can be seen. Take to the streets defensively and always run towards traffic.
