Hello. I went for a pleasant 6 1/4 mile run yesterday. I tracked it using Map My Run on my iPhone. But I thought that my pace recorded was a little too fast for the amount of effort I felt. So I checked it out on the computer using the map my run website and my actual run was three fourths of a mile shorter than what I actually did! Bah! So, has anyone ever compared the results of map my run versus run keeper? Do you find one more accurate than the other? Also with these applications compared to the GPS watch like a Garmin, are they more are less accurate or about the same? I had some fairly accurate distances recorded with map my run in the past. But in the half marathon I did a few weeks ago and in the case of yesterday's run it was way off. The half marathon was off by over a mile and not in my favor.
