Be careful where you run. Choose locations that are safe, with lots of people around and as few cars as possible. Choose a good time to run. Running at night or in the morning, before dawn, is much more dangerous than running during the day. You run the risk of getting hit by a driver that can't see you or someone taking advantage of you when fewer people are around. Stay visible to drivers. If you do decide to run near a road, stay visible by wearing bright, reflective clothing. You can also get safety devices, like a blinking LED, to get even more attention. Jog with a buddy. Whether jogging with a person or even just a dog, this is significantly safer. This will help keep you safe from people who may want to take advantage of you! Do a test run. Do a basic jog and see how it makes you feel. Test how far you can get before you feel super gross. By setting realistic expectations, you'll be much more likely to succeed. Don't forget about getting back to your starting point. Factor in how long it takes you to run and leave in time to get back to your starting point. Yes, you may be able to get to that coffee shop down the road, but what about getting back? Slowly increase your distance over time. Remember, you'll be able to jog a greater distance once you're in better shape and can move farther, faster. Work your way up to it. Increasing will also give your body a better workout, so keep a longer route in mind. Use mapping software. You can use free tools like Google Maps or RunningMap.com to measure the distance of your route and track things like elevation changes. Some websites even have a social aspect, allowing you and other runners in your area to share and compare routes. Account for terrain. Changes in road types, terrain changes, and elevation changes can be a bigger hurdle than you give them credit for. Try to avoid things like having a steep hill right at the end of your run. You'll increase the chances of hurting yourself. Test it out. Once you think you've got a good route in mind, test it out...
