In an effort to “bridge the physical and digital worlds,” RunKeeper is introducing the AirDrop sharing function in its iOS 7 app. That means if you see someone at a race using RunKeeper and you want to keep tabs on their activity in the future, you can AirDrop them a RunKeeper friend request!
Similarly, your running buddies may want to follow the same workout routine you’ve created in RunKeeper. Just select an existing workout or create a new one, and hit Share with AirDrop once you’re in the workout. Now you and your friends can follow the same interval plan, but at your own pace.
