10.9 
Santa stuffed a little bicycle odometer/speedometer thingy (called a 'cycle computer' on the packaging) in my stocking a few weeks ago so now I am able to measure more accurately the distances I cover when biking. Since I was born with flat feet and I can't run very well (even in high school the smokers would beat me in the mile. I could barely do it in under 10 minutes then), so biking is how I exercise.

It turns out my standard route is 10.9 km, or about 6.5 miles, round trip. I had estimated about 5-6 miles going by the mile posts on the path and then adding in the route to the path that runs along the river and is only about a 1/2 km from my house. The terrain locally is fraught with hills and it's uphill to my house so it's a hard 10.9 too and it's steep enough that I have to walk some of it on the return trip home. Some parts of my usual ride are difficult to maintain a 20 kph speed.

Anyway, the device is called a 'cycle computer' because it also tracks your speed, distance, average speed, calories burned, tells the temperature, and a few other things. On my last ten-point niner, the computer said I burned 355 calories which doesn't seem like a lot. I think taking the terrain into account, I can add at least 75 to that. Still, though, 430 calories is only a few beers or a hot dog. I know you burn calories throughout the day doing the daily things one does and little things can help. One thing I never do is take the elevator. Four floors or less, I walk it, unless it's a situation where the elevator is the only option, or I have the kids and strollers and such with me.

In the warmer months, I try to bike at least three times a week. In the winter and early spring, I have to sneak in a ride when weather permits. Exercise is important. More Americans should do it.
