Starting this week, my runs outside are not showing any elevation. Same run a week ago shows the elevation gains correctly - about 500 feet over the length of the course. Is this a known problem with Garmin Connect?
There is also a post about this in the Forerunner 15 forum. I am having this exact issue with my watch. October 26th workout had elevation data, October 28th workout had none. I think perhaps the dates are because they're all workouts that I sync'd yesterday, hadn't had a chance last week.
I am really hoping they can add the elevation data back into the logs, I ran my big marathon on Sunday and really want all my data!
The last time it happened there was no retroactive correction to the elevation data. It just started working again after a week or two and I never got credit for my hills!
