Bicycling geekery

This post is for those interested in bicycle geekery and data tracking. Although I'll see if I can sneak in a picture of a cute baby as well. What would a blog post be without one.

It's also for Grandpa Doug, who very kindly gifted me with an awesome new bicycle computer at Christmas time. This thing does it all but turn the pedals for you. Simple things like speed, time, elapsed time. Cycling specific stuff like cadence. Heart rate monitor. With the addition of GPS, it handles routing as well as display grade.

I've been playing with it while pedaling on the trainer inside. This morning was sunny, gorgeous... and 20 degrees F. Inside again.

Fortunately, I have some video distractions. I've been watching the recon video of the 2009 L'Etape du Tour, an organized ride that lets you try out one of the stages of the Tour de France. In 2009 the route included the Giant of Provence, Mount Ventoux. The recon video produced by Cyclefilm was filmed in the autumn of 2008 and the scenery is just gorgeous. Makes it a little easier to bear pedaling in place, inside.

I've got a half-dozen or so rides on the computer, here is just a small bit of the data from the computer:

As you can see, I need to tweak the cadence sensor. I was actually pedaling the whole time but it seems to drop out as I go along. The display would also show a map of my route, but since I wasn't actually moving (save for through the hills of Provence in my mind's eye) I took that bit out. I'm looking forward to using the computer once I actually hit the roads this spring.

And here's an outtake from the recon video:

And a gratuitous tip o' the hat to the small lad.

that bottom graph looks like the spectrum of a broad absorption line quasar.
