I have the first part of my new Python project (reading and analyzing data from my Garmin): it can now extract (or calculate) distance, time, moving time, maximum speed, average speed, average moving speed, maximum and average heart rates, time in each heart rate zone, and calories for the overall ride and each lap, as well as a linestring of the path taken, and starting points for each lap. For now I only store some of these in my database, but I may add them later — that’s a database task. Here is the output for a ride where I hit the “lap” button a lot:

Done
There’s a little room for improvement — rounding errors cause a few problems with moving vs total times in some laps, for instance — but this is what I’m looking for. My next question is: do I want this to be a standalone program, with its own GUI and everything, or do I want to build a web interface?
