Early days, but opted to just record ride with Edge. It looks like all the data goes into Garmin Connect and, like kindly noted above, apparently Physio Trueup allows the data to be accessed from the watch.
I did try creating RWGPS routes to give it a try. Both rides are out and back; one is pretty steep and the other flat. I was particularly interested in the ClimbPro feature on the Edge. It did show up in the hilly ride, but the location of the climbs was off by miles. I am pretty sure it is because of poor satellite reception in the fjord (this is at the end of the longest fjord on North America). The other route is too flat to trigger ClimbPro. I will wait until I get to America and try a hilly course again. This is, of course, using the GPS capacities of the Edge and not the greater satellite potential of the watch.
The comment that the learning curve will be steep is correct. But it is fun. Thanks one and all.
