Keep track of your treks on iPhone 3G

RunKeeper ($9.99), new to the App Store, lets iPhone 3G help you keep track of your “runs, hikes and walks,” says John Biggs (nytimes.com). While you’re out, “RunKeeper displays the current pace, distance and time as well as a bar graph of the speed over time.“ Then, it “automatically uploads the data to www.runkeeper.com. Log in there to see a Google map of the route as well as the run’s total distance.” (link)
