Performance data

I upload my run data to the Nike+ website (top) which provides a personalized page that tracks my history. It keeps track of total number of runs, total distance and average pace. You can look at each run separately as well. You can also set and track goals, participate in discussions and challenge other Nike+ users. MapMyRun provides similar functionality but doesn't require the use of the Nike+ system. You can import your data from the Nike site to MapMyRun (directly above) and see much more detail about the run than Nike provides.
