The easiest way to be known while you run is to run with a friend (or five). If you do find yourself in a sketchy situation on a solo run, however, being able to let others know who and where you are can be the key to staying safe.
Using an app like React Mobile allows you to share your location with selected friends or family, and a quick swipe on the screen lets you update your status from "I'm fine" to "Follow me" if you start to feel nervous for any reason. Hitting the "Help me" button lets your network know something has gone wrong.
Backing up your tech-based safety measures with an on-body identification like the Road ID wristband ($20-$30) or shoe ID ($20) ensures that if you end up in a situation requiring any assistance, you'll be able to get the help you need as efficiently as possible. We also recommend always running with an ID on you.
