I have been comparing notes with some fellow riders who are Garmin users but use sites other than Garmin Connect and I really liked some of the features that I saw.
"Map My Ride" has a cool feature where climbs are catagorized (Cat4-Cat1), which I think would be awesome to have as part of Garmin Connect
and
"Ride With GPS" has a feature where % grade is reflected along with elevation when scrolling through the route profile.
I don't know how difficult it would be to add these features. I know that Edge 500 already calculates %Grade so hopefully that would be an easy fix, but I think that these features would make a huge difference in the quality of the site and I am pretty sure that it would attract more riders to use Garmin Connect vice other utilities.
Thanks.
