I know you're into fitness and I commend you for your efforts. Walking is great exercise. However, please remember that it's still dark outside at 6:05 AM these days. And walking side by side by side in the road may not be your safest option. Our neighborhood has sidewalks. When you see a car coming, please use them. Also, black may not be the best color to wear before sunrise.
A strong, healthy heart does you no good if you're not going to use good common sense. After all, what good is fitness if you're just going to end up as a greasy spot in the road?
