I had an errand to do today. Here is what my ride looked like on the return trip. Red is elevation and blue is speed. The speed is not entirely accurate though because as far as I can tell, the program that made the log only takes a position reading once every 6 seconds and Google Maps figures out the speed based on how far each point is and the difference in time and the GPS does not always give the correct position. It can be off by 10 or 30 meters sometimes.

When I first started, this would have wore me out quite quickly.
