I read Runner's World's website. It's usually not awesome. Today it was awesome.
An excerpt (which I just realized is an excerpt from a book I'm going to have to read now):
Running Rules of Thumb
1. If you see a porta potty with no line, use it. Even if you don't need to.
2. If you have to ask yourself, Does this driver see me? The answer is no.
3. If you have to ask yourself, Are these shorts too short? The answer is yes.
4. 1 glazed doughnut = 2 miles
5. You rarely regret the runs you do; you almost always regret the runs you skip.
6. Not everyone who looks fast really is, and not everyone who looks slow really is.
7. Nobody has ever watched Chariots of Fire from beginning to end. Not even the people who made it.
8. You can never have too many safety pins on your gym bag.
9. Running any given route in the rain makes you feel 50 percent more hard-core than covering the same route on a sunny day.
10. If you care even a little about being called a jogger versus a runner, you're a runner.
