Running safely comes down to being visible, aware and prepared. Wear bright or reflective clothing and lights in low light, run facing oncoming traffic when there is no sidewalk or path, tell someone your route and expected return time, and carry ID, emergency contact information and a phone. Keep music low or use one earbud so you can hear your surroundings, adjust for weather such as heat, ice and lightning, and trust your instincts: if a situation feels wrong, move toward busy, well-lit areas and call for help if needed. These simple habits make most runs safer without taking away the freedom that makes running enjoyable.

Be visible
Drivers, cyclists and other path users need to see you, especially at dawn, dusk and night. Wear bright colors during the day and reflective materials in low light, ideally on moving parts of your body such as ankles and wrists, which catch drivers’ attention. A headlamp helps you see uneven ground, and a blinking red or white light makes you visible from a distance. Remember that drivers may be distracted, dazzled by low sun or have limited visibility in rain and fog. Never assume a driver has seen you; make eye contact at crossings before stepping out.
Run smart around traffic
Where there is no sidewalk or path, run on the side of the road facing oncoming traffic so you can see vehicles approaching and react if needed. Use sidewalks, paths and parks whenever possible. Obey traffic signals and cross at designated crossings. Be cautious at driveways, parking lots and intersections, where drivers may be looking for other cars rather than pedestrians. On blind curves or hills, consider crossing to the side with better visibility, then return. Run single file with friends on narrow roads.
Plan and share your route
Tell a friend or family member where you are going and when you expect to be back, especially on long runs, early mornings, evenings or trail runs. Many phones and running watches allow live location sharing, which lets trusted contacts see where you are. Varying your routes and times can reduce predictability. Before running somewhere new, look at a map, note safe places to stop, such as shops or busy areas, and check for trail closures or construction.
Carry ID and a phone
If you are injured or become unwell, emergency responders need to know who you are and whom to contact. Carry photo ID or an ID card or tag with your name, emergency contacts and important medical information such as allergies, conditions or medications. Some runners use ID bracelets or shoe tags. Set up the emergency information feature on your phone so it can be accessed from the lock screen. A charged phone lets you call for help, navigate and contact someone if you need a ride home.
Stay aware of your surroundings
Headphones can make runs more enjoyable, but they can also block important sounds such as traffic, bicycles and people calling out. Keep the volume low, use open-ear headphones or wear only one earbud. On busy roads or shared trails, consider leaving music at home. Scan ahead for hazards such as potholes, ice, roots and uneven sidewalks. Avoid staring at your watch or phone for long periods while moving.
Personal safety
Trust your instincts. If a person, vehicle or situation makes you uncomfortable, change direction, cross the street, head toward busy and well-lit areas or enter a shop or public building. If you feel threatened, call emergency services. Running with a partner or group adds safety and company, especially at night or in remote areas. Some runners carry a personal alarm or whistle. Choose routes with good lighting and regular foot traffic when running alone in the dark.
Dogs and wildlife
Most dogs are friendly, but some may chase or react to runners. If a dog approaches, slow down or stop, stand calmly, avoid direct eye contact and give it space. Speak in a calm, firm voice and do not turn and sprint away, which can trigger chasing. Walk away slowly once the dog loses interest. On trails, learn about local wildlife such as snakes, bears or other animals, and follow local guidance on what to do if you encounter them.
Weather safety
Adjust your running for conditions. In heat and humidity, run early or late, slow down, hydrate and watch for signs of heat illness such as dizziness, nausea, headache, confusion or stopping sweating. In cold weather, dress in layers and protect extremities from frostbite. Watch for ice and shorten your stride on slippery ground. During thunderstorms, weather services such as the U.S. National Weather Service advise that when thunder roars, you should go indoors, since no place outside is safe from lightning. Wait at least 30 minutes after the last thunder before heading back out. On days with poor air quality or wildfire smoke, consider running indoors.
Trail running safety
Trails bring extra risks because help can be farther away and phone signal may be weak. Download maps or use a navigation app with offline maps, and learn the route before you go. Carry more water and food than you expect to need, plus a light layer in case the weather changes. Watch your footing on roots, rocks and loose ground, and slow down on steep descents. Let someone know your exact trail, trailhead and expected return time, and check in when you finish. Carry a whistle, which is louder than your voice and uses less energy if you need to signal for help. For remote or mountain runs, consider a small first aid kit and a headlamp, even if you plan to finish in daylight.
