Nikeplus.com just got a major site upgrade. As a result, Nike+ workouts cannot be imported with RunningTracker anymore.
I have to analyze how I can make RunningTracker work with the new Nike+ version.
In the meantime, enjoy the new Nikeplus.com website!
[Update] Running Tracker is now working with the new Nike+ version! See the new post: http://runningtracker.tuxfamily.org/blog/2012/07/18/running-tracker-2-2-1/
