For those of us who move from Point A to Point B via motorized vehicle, the most important thing to remember on Saturday is not carb-loading. No, it’s road closures. That’s right. Sunday is the (unwieldly titled) PF Changs Rock ‘n’ Roll Arizona Marathon & 1/2 Marathon; I’m out of breath just typing that. That means thousands of insanely in-shape people will be running — for hours at a time, mind you — around our streets in the Valley.

So you may want to check out the marathon’s official Web site for information on road closures ^[1].
