How do you people measure elevation? Or how do you get an accurate reading from a garmin? I always ignore the elevation part of my garmin as I don't beleive it at all. Recent run was 7 miles and according to garmin it had 599m (1965 feet) of ascent and roughly the same decent. This would give a Stinker rating of 280%. Except the run was mainly along a canal toe path and very very flat.
(Looking at the elevation graph and estimating ascent as 50 m 164 feet gives a more realistiv rating of 23%)
Hi Catalin
The Garmin is usually pretty accurate - a few thoughts...
Make sure you are looking at "elevation gain" (simple I know but hey...)
If you finish where you start, check that "elevation gain" and "elevation loss" are the same (ish) they should be
Any odd factors - did you lose touch with the satellite under a canal bridge (toe path run??) etc
Finally, I run the same run a few times and know which is the correct reading (eg 364, 366, 859, 366, 363 = one rogue reading)
Hope these meanderings help!!
