Summer isn’t over quite yet, so if you’re still looking for a little motivation to get you back in tip-top shape Nike added a new Challenges feature to its running app.
To start a challenge in Nike+ Running 4.3, simply set a distance and send the invite to your Nike+ friends. The app will keep track of who’s in the lead and if you win you get a shiny digital medal to show off to your momma.
The free app is available in the App Store now for both iPhone and iPod touch.
