The Nike+ GPS iPhone app should is an ideal purchase for the avid runner. CNET offers a guided tour.

Kent was a senior managing editor at CNET News. A veteran of CNET since 2003, he reviewed the first iPhone and worked in both the London and San Francisco offices. When not working, he's planning his next vacation, walking his dog or watching planes land at the airport (yes, really).
The app's primary screen shows your current stats for all runs that you've taken. You then can choose to start a new run or challenge yourself to beat your last run.

Summary
The summary tab shows time, distance completed, calories burned, and average pace. You're also presented with options for viewing the route, rating your run, calibrating the distance, or connecting to the Nikeplus.com Web portal.

First run distance
The maps use a standard Google Maps interface. Mileage is marked with flags.

First run pace
The pace view uses color shadings to show your pace changed throughout your run. Green denotes the fastest segments, whereas red shows where you ran slower. Yellow and orange are for in-between areas.
I wish the app showed elevation changes while you're running and factored them in when determining your pace. Corona Heights, which is the area in the bottom-left corner, was the hilliest part of this route.

Second run distance
As mentioned in the review, gaps appeared in the map the closer I zoomed in. I can't explain the reason for them.

Second run pace
Also, pace information wasn't always accurate. Note, the large red area in the upper-left corner, for example. Perhaps I lost the GPS signal, but I know that I wasn't walking there.

Go by distance
If running for distance, you can travel anywhere from one kilometer to a full marathon. Here again, you can set your own distance.
