I have realised why I never finish anything - it is far too easy to get distracted by another little job.
This time my daughter asked me how far we had climbed after a very hilly bike ride on our holidays.
I was a bit disappointed that I could not give an instant answer, as I had a track log from my Garmin Etrex GPS device, which includes elevation data.
Therefore that evening I wrote a little program in Python to analyse GPX files and provide some basic statistics on the route - this can be found at http://code.google.com/p/wherewasi.
