Just want to chime in that I also came across this today while preparing for an upcoming mountain trail 100k race. This is my first race using a Suunto watch instead of COROS or Garmin. It’s disappointing to:
a.) not have an elevation profile in Suunto when importing the official GPX file (from UltraPacer, in this case)
b.) not be able to use turn-by-turn guidance
With COROS and Garmin, both of these things are non-issues for their users. I understand the bits about the GPX file not containing the elevation data itself, how I can find a workaround, etc., but this should not be my problem, and it never was before. And I don’t know of any fix to get myself turn-by-turn guidance, which would be great when running in the mountains at night, other than to spend hours completely recreating the route myself.
