Nike has released an update to Nike+ GPS adding social networking integration. In addition to allowing users to share their runs via Facebook and Twitter, the new version also introduces a new Cheer Me On feature that allows users to post on Facebook that they are going on a run and then receive mid-run encouragement in the form of notifications each time a friend comments on their status.
Other new features allow users to view their best runs from within the app and push past their goals by playing one more PowerSong. Nike+ GPS is designed primarily for iPhone users but also supports the iPod touch without the mapping capabilities.
Nike+ GPS requires iOS 4.0 or later and is available from the App Store for $2.
