I'd just like to thank the kid in my development who was out walking his dog and sneaking a cig while I starting off my morning run. Nothing's more gross than inhaling smoke while you're running. (I really don't know how people who run in cities deal with that--plus city bus fumes, smog and more.) I took off as fast as I could to pass him. And then I slowed down, but I still ended up running faster than I thought I could the rest of the four-mile loop.
I'd probably do pretty well in a race if I could get the people at the water stations to light up so I'd want to pass them instead of slow down. You never run so fast as when you're trying to run away from something, after all.
