Why do I care?
- First, I care because I care about openness.
- Second, I care because their analysis software is pretty fancy, but does not happen to be what I want. That is why open data is important.
- I want is to be able to look at the relationship between work performed and heart rate. I can do that with the GPS distance and altitude information plus heart rate -- not perfectly, but better than with distance alone.
I sent Garmin a request for help on this; perhaps they will send me the internal format they use.
