Imagine you are running the London marathon, everyone you wish to tell can be tracking your progress from anywhere.

Practice, Practice, Practice - There are many possible setting combinations find which work best for you.  Ideally you should be testing this in your 3 or 4 long runs before you begin taper.

You must select a Map.  It is possible to select any map but it will be a poor experience for the people following you if you choose a map different than the one you are actually running.  The program zooms to the runner location if your location is not within the marathon map the program will be zooming a lot.  

You can run the program in Automatic or manual tracking mode.  Manual tracking means you press the 'Send Location' button whenever you wish to send the location.  The program will try for 10 seconds and send the most accurate position it finds in that time before reseting and waiting for you to press the button again.

In Automatic tracking once you start tracking the program will continue tracking until you stop tracking.

The Minimum Battery setting allows you to specify a value which will stop automatic tracking.  This is to enable you to have a some battery remaining for celebration calls after the race.

You specify how accurate a position you wish to send.  Valid values are 10m, 50m, 100m and 1km.  The more accurate a position you request the more battery power will be used.

You specify a distance filter which tells the location manager how far you must travel before sending a new location.

In order to follow your progress around a course you need to email your Tracking ID (UDID) to whoever you wish to follow you.

The transmitted data section provides information on what information is sent to the server.  The suggestions section has tips for Battery usage and general program Usage.

The tracking screen has a very simple interface.  One button that toggles between 'Start Tracking', 'Stop Tracking' and 'Continue'.

When tracking is stopped the background of the screen is red.  When tracking is running the background of the screen is green.  When the background of the screen is yellow it means the program has stopped tracking because the battery level has fallen below the minimum.

The current battery level is shown.  The iPhone reduces the battery status in 5% increments.  If the battery level is less than the minimum setting level and you are in Automatic Tracking mode then you will get an error message when trying to start tracking.

Every action in the program is considered an Event.  Starting tracking is an event and is stopping tracking.  Other events include putting the program to sleep, waking the program back up, finding a manual position, finding an automatic position, transferring the location to the server, location transfer to server failing, location errors.  Each event is written to the log file.  The total number of events is shown on this screen.

Every time an automatic location or manual location is found the number of locations on this screen is updated and is the time of the last location.  The time is an easy indication of whether things are 'still going well' or not.

The log view on the far left shows all the events recorded while tracking.  Note that the log information is only available when you are not tracking (the button is disabled).  You can see the more details screen on the left which you get when selecting a line.  Clear Log removes all the entries from the log.  Delete Tracking Data removes your location record from the Internet.  Note that after Delete Tracking your position will be unavailable to whoever is trying to follow you.
