Garmin Edge 1040 Climbpro issue

Climb pro is basically dependent on the quality of the source of your route file. Although in the current beta version there've been improvements to climb pro and especially gradient and altitude calculation.

I downloaded the route file from Strava, would it make a difference if I plotted the route myself on Strava ? 

Thanks 

I've never used Strava for that, but you could try Komoot. Or, import the Strava route to Garmin Connect first and then transfer to the Edge. Possibly there could be a difference.

I try that method next time I plan a route. Thanks. 

I create my routes on Garmin Connect.  Others use Strava, or Komoot, or MapMyRide, or RideWithGPS.  I've heard of other route generating web sites, but I haven't used them.

Maybe I'll try generating a route on four or five different sites, and try to see what differences can be seen.

There is a very long (35 Pages) discussion here regarding gradient lag and related issues on the climbpro screen including position on the climb page but the end conclusion is that the current beta version 15.17 has fixed these problems to most peoples satisfaction, so maybe your too? Maybe try the beta? From change log  (15.13) Improved ClimbPro data screen and climb list

I’ll try the beta version and see if this makes a difference, thanks .
