I went for a ride up a hill nearby (mostly to partially drain the battery for balancing) and I logged it with the Geo Tracker app (by Ilya Bogdanovich) for Android. I started and stopped the record in my driveway.
I find the altitude data rather confusing though.
Altitude difference | 120 m |
Max altitude | 103 m |
Min altitude | -16 m (there was one stretch lower than my driveway) |
Vertical ascent | 160 m |
Vertical distance | 309 m |
Vertical speed | 0.15 m/s |
I would've thought that "altitude difference" would be from "altitude min" to "altitude max", or 16+103=119
I have no idea where the numbers come from for the last three.
[later] Ah. I can make a screenshot and attach it.
The biggest climb is going along the straight "pot handle" section from the lower left corner of the lake up the turn-off to "Beech Hill Park".
The side-trip through "Ogden Mill" was on the way back.
