I used both my Edge 800 and my 1030 for my walk today. The 800 showed 1.01 mile while the 1030 showed only 0.34 miles. Both are set to smart recording and auto pause off. The sum of distance in the fit files show 5376 ft for the 800 and 5392 ft for the 1300. Very odd that an old 800 works fine while the new, only a month old 1030 is in err.
