I'm amazed at how much of a difference MB Gravity (elevation correction on Motion Based) makes on elevation measurements. Here's two runs on the same out-and-back course (which should have a symmetrical elevation profile).

Here's the un-corrected version (directly as the Garmin sees it):


Here it is corrected by MB Gravity:




Huge difference! If you use Motion Based, bu sure to turn the corrections on. I was especially concerned about the huge 300' cliff around the 3.25 mile mark. You think I would have remembered that. Tongue

The latest beta of Sporttracks has a plug in that does similar elevation correction.

Not sure the elevation data is even worth looking at without it.
I ran a mile and I liked it, liked it, liked it.
