A really long, fast and high walk

Karen has been doing a lot of walking recently.  She goes 6, 8, 10, even 12 miles at a time.  She's getting stronger and feeling better and working hard.

She uses the My Tracks program on her Android phone to measure her walks.  The GPS feature captures all relevant data and she can upload it to a spreadsheet in Google Docs.  Pretty convenient.

But on a recent walk, the program may not have worked so well:

Take a look at those numbers:

  • Just under 170 miles
  • Average speed of 223 miles per hour
  • Elevation change of 14,443 feet

Hmm.  Seems a bit unlikely.

Yet when she checked the map in My Tracks, it said she had gone from Lafayette to just past Fresno:

I guess technology doesn't always work quite the way it should.
