Let me know if you want the GPX files of the two Strava HC climbs below…
- About 6.5 months ago I wrote this about a Strava course on my Garmin 530:
and yes, it was a course synced from Strava.
worked perfectly on first 3 sub-climbs of a long HC climb. Simple out-and-back course. Issue happened on the descent, which had two short climbs.
- About 8 months ago I did an HC climb on this Strava course:
and it was a single climb on my 530:
No issues with ClimbPro, the climb finished at the top exactly as per the course. The barometer however only give me 5266’ climbing, but thats how barometers roll sometimes 
- Couple weekends ago I rode a course synced from RideWithGPS and no issues with ClimbPro.
