Move over Nike+ Runstar is here. Runstar takes a different approach to tracking your runs by plotting your GPS location over time. When you’re done with your workout you can even see your results plotted on the map. Runstar also allows your to set goals, track your times, track your speed and even track your elevation. The UI looks to be borrowed from the iPhone and we have no gripes with that, it looks great. The best part of Runstar? it’s completely free.
