Only Start & Finish controls have been defined - draw your own
course, and add time in the format hhmm .
This means the track will be shown very quickly on the animation,
but the full track will be shown. If you enter your time as mmmmss
(hint there are 1440 minutes in 24 hours) the animation display may
not work as it is not designed for long events.
The map is georeferenced so GPS, if available should load easily,
but may need to be broken into 3 parts to avoid the 11 hour limit on
tracks.
