Tested out a GPS iPhone application called EveryTrail. Merits further tests.
The application seems pretty accurate: I didn’t follow this exact path, but 95% is close enough. All you do (once you have set up an account) is launch the program, give your trip a name, and then start walking. Every nth seconds, EveryTrail checks in, logs your location via GPS until you tell it to stop.
