Hello,
I only practice MTB. I changed my Edge 820 for an Edge 1030 and i'm really disappointed by the "round trip routing", with or without Trendline Popularity routing option activated. It was much better on my Edge 820 and i don't undertand why, because i have exactly the same maps (Topo Pro and Garmin cycling one).
When i create a round trip course for MTB, the Edge 1030 will suggest routes with a lot of km/miles on concrete roads and so few on specific MTB ones. It doesn't do the job ! It was not so bad previously with the Edge 820.
And what about the supposed "Trendline Popularity routing" that should leverage Garmin Connect data to determine the best and most efficient routes ? Absolutely not working from my point of view, again for MTB use, i did a lot of course creations, trying to change distance and direction parameters, but the result is the same, neither course was relevant.
Do some of you experiment the same or not ?
JM
