The first part of today’s activities I knew would be problematic for the pedometers: we went biking at Coopers Rock. It’s amusing how far off each device is from every other device.

But, I had my GPS, so I got all that information.

Then I realized that when we walked to dinner, I should take the GPS! Further proof the Withings Pulse can’t calculate elevation for shit!

First up, what Withings recording for me elevation today, all day:

From the time period of 3:30 to 5:30, it gives me an elevation gain of 119 feet.

And now, what the Withings recording for Michael. Keep in mind that we spend the entire day together.

Now here’s what the FitBit recorded for Saturday:

Then numbers aren’t directly compatible, as the FitBit displays the data is flights of stairs. But you can see the trend.

Here’s the route recorded by GPS:

According to my GPS, my elevation gain for the entire trip was 310 ft. So the Withings gave me about a third of the elevation I actually had.

So, compared both to the FitBit and to actual GPS measurements, the Withings Pulse has been giving me only about a third of the elevation it should if I’m climbing hills (versus climbing stairs–it seems to get the stairs fine).

BAH HUMBUG.

Oh, in case you were interested, here was our elevation from our biking at Coopers Rock:

And here’s the route:
