12 - 1,709 ft. - 1:53 on feet
30 min hill workout which consisted of 30 minutes up at roughly marathon effort and then 30 minutes down at a controlled pace but still running. Overall felt good. I didn't push it as hard on this workout as I did a couple weeks ago on a similar workout. I wanted to stay more near the marathon effort where before I was pushing the effort harder and was spent by the end of the climb.
Up - 3.16 miles - 807 ft. - 30 minutes
Down - 4.13 miles - -1,086 ft. - 30 minutes
So, Garmin provides elevation corrections based on professional surveys for runs. If however your device has a barometric altimeter, those corrections are turned off by default. The above elevations are based on my device which has a barometric altimeter. Below are the numbers based on the surveys. Would be interesting to know which is more accurate. Quite the discrepancy. Also, all of my runs up until today have been based on the professional surveys because today was my first run with a barometric altimeter (Fenix 3).
Overall elevation - 2,425
30 min up - 1,021
30 min down - -1,447
Now I don't know which is more accurate or which to use for my weekly totals. I just went through a few of my past runs and when I turn off the corrections, sometimes the total elevation goes up and sometimes it goes down. So...who knows. My assumption is the barometric altimeter is more accurate than elvation based off of GPS (articles I have read support that assumption), but I don't know about how accurate the "professional surveys" are that Garmin is using.
