I use GC to share rides, and I like it for the ease of use. I've had mine for about a year, and i agree, the new site looks way better, too. Never shared data before (too cumbersome) and now i do fairly regularly. Hadn't thought about how i'd published a map to my front door, though. Funny.
With the 305, the old software let you compare each data set against another, as in elevations vs. time, elevation vs. distance, elevation vs. heartrate, heartrate vs. distance, etc. The new GC just has a couple of settings, though. Does anyone know of any software for the 305 that still lets you pick what you can analyze?
