A set of DataField developed using ConnectIQ SDK. I'm owner of an Edge 520 and a ForeRunner 235...
What's lap elevation? I love climbs.. and most of my time I'd like to known how many meters uphill I traveled from the start of climb. The only "option" that I have on my "climb screen" is the elevation+ field available on device and it's all. I downloaded the SDK and wrote it.
Simply the time elapsed for each mile or km (based on device settings)
Calculate slope in two ticks..
How use this field on your Garmin? It's simple. Compile it and transfer the prg file into /Garmin/Apps folder.
