Outside

Sunny with Afternoon Thunderstorms

I remember an ad for outdoorsy-type shoes (by Nike?) from some years ago (1995?) that claimed “Americans spend 1% of their lives outdoors.” I’m also pretty sure Nike (or whoever) omitted time spent travelling in cars, or going to and from cars, from that 1% figure. My memory is pretty hazy here, and Google is surprisingly unhelpful. So I might be misremembering.

However! At the time (1995?) it certainly didn’t seem unlikely that Americans really did spend 1% of their lives outdoors. And remember, this was before the Internet was actually interesting so the number may have declined in the interim. At the time (1995?), I was practicing archaeology, which occasionally meant spending as much as 100% of my time outdoors, if you consider sleeping in a tent to be “outdoors.” So on the subject of this particular (hazily remembered) Nike (or whoever) shoe (or whatever) campaign, I could feel a certain sense of moral superiority.

Which leads me to wonder, how much of my life now do I spend outside? Here’s a quick back-of-the-envelope calculation (do I make any other kind?)

In every 24 hour weekday, I always:

  • Walk the dog for 30 to 60 minutes (total)
  • Ride my bike at least 60 minutes (total)
  • Walk to the coffeeshop in the morning and afternoon (15 minutes)

On a “typical” weekday in weather that isn’t pouring down rain I’m also likely to:

  • Ride my bike an extra 10 miles or so (+45 minutes)
  • Walk or ride my bike to the grocery (+15 minutes)
  • Take a lunchtime bike ride downtown (+30 minutes)

So for my usual weekday activities, in pretty good weather (10 months of the year in Portland), I probably spend about 210 minutes outdoors, which is about 14% of a 1440-minute day.

My weekends — especially since Orion’s arrival — are seldom “typical” in any sense, so I’m going to try to pin down a minimum here. This will involve a lot of handwaving I’m sure. But on any weekend I’m pretty likely to do the following:

  • About 90 minutes of yard work
  • 120 minutes of dog-walking
  • Perhaps 60 minutes (as a rough average)1 of bike-riding

So in a 2880-minute weekend, I’m spending at least 270 minutes, or 9% of my time, outdoors.

I don’t think I lead an excessively outdoorsy life, but it looks like I’m al fresco 9 to 14 times more often than Nike’s putative average American. That seems fishy. If the average American spends 1% of their time outdoors (omitting time spent going from car to door and vice versa), that pencils out to just 14 minutes a day.

Do you think most Americans spend less than 14 minutes/day outside?

And does anyone else remember that ad campaign?

Notes

1 This is a really rough average, especially now that Orion is here. Pre-Orion, I might have gone two or three weeks without a significant ride, with a four to eight hour monster in the middle.

Eight Miles

I changed my clipless pedal cleats today.

Time for new cleats

I remembered doing this last autumn, right around the time I rolled my odometer over 6666.6 miles. I have the photos to prove it:

EEEEEVIL New Cleats

Which occasioned me to wonder, how many miles have I ridden since that time (September 9, 2007)?

7660+690

Well, as of about 20 minutes ago my bicycle odometers (I have two — one for each bike) read 7660 and 690. I seldom ride without a computer, and they’re pretty accurate. Years ago, I calibrated the one that reads 7660 by rolling out my bicycle tire alongside a tape measure. I use the stock calibration for my tire size on the new computer, but its distances pretty much agree with the old one.

So I’ve ridden 1684 miles in the last 209 days, averaging just slightly more than 8 miles a day or 56 miles a week. At this rate I can expect to ride about 2933 miles in a year. That’s kind of a disappointing distance ... I aim to get more than 100 miles a week in good weather. On the other hand, this has been the wettest winter on record in Oregon.
