It is now 12:04am, and I just got back from a walk.

There are a few things about this walk to make it notable:

1. I got up from my desk at 11:35pm and headed out for a brisk walk, mainly so that I could try to get over 6,000 steps today.
2. I measured my steps using a Fitbit, and had the specific target because it’s part of an internal fitness challenge Automattic is hosting through Keas.
3. I took the chance to compare Fitbit to RunKeeper for measuring walking (mainly looking at distance accuracy, but also at calorie burn).
4. A guy (probably high) most definitely lined me up to attempt to mug me, he even tried to walk with me/talk/engage to distract me and get me to stop, but I out-walked him and he kind of gave up.

So; fun stuff all around. Here’s the data, from RunKeeper:

and for the same time period from Fitbit:

What’s interesting here?

• FB reports that I burned 163 over RK’s 126; that’s a 23% difference.
• FB reports that I covered 1.22 miles, while RK reports only 0.76 miles. Almost 40% difference.
• Pace is barely even worth comparing when distance is so differently recorded. Time even shows as 40 seconds different, although I’ll give FB the benefit of the doubt and assume it’s rounding.
• You can actually see the part where the guy approached me, because I sped up. If you look at the map from RK, it was on Larkin St, between Broadway and Pacific. He tried to “walk with me” so that he could get me to stop, but instead I just walked faster. I topped out right there at 14.4 minutes per mile according to RK (just over 4 miles per hour).
• If I hadn’t been trying to meet a daily fitness goal, I wouldn’t have been walking around at midnight, making myself a target for getting mugged

Maybe I should run instead of walking, since high/homeless/whatever people are even less likely to give chase?
