Today, I walked for 46 minutes and according to the pedometer app on my phone, I walked 3.75 miles for a pace of 4.9 mph.  

That didn't sound right, so checked in the GPS map, I saw it had me going zig-zaggy back and forth, sometimes backtracking.  It had done that once before, I don't know what was up with it.  So don't believe the distance or mph for a second, but the time walked was at least correct.
