The Nike+ GPS iPhone application that I have blogged about is free in the iTunes app store for a limited time.
Nike+ is celebrating its fifth anniversary. The other day I had a problem with the GPS app -- it lost me. (This is the first time that has happened to me.) So, when it updated my Facebook feed for me (automatically) I was sure to add that even though it said I ran 5 miles, I really ran 6.
Which got me thinking about pre-Nike+ technology. When I trained for the marathon in 1999, if I needed to run 6 miles, I'd drive 20 minutes to go to Lady Bird Lake and run probably a 4 mile loop, then to the 1 mile marker and back. (At the time there wasn't a 3 mile loop.) With this app, I just walk out my front door and run until it tells me to stop. It's extremely freeing, and such a time saver now that I have even less time in my life.
So, go download it now while it's still free!
