First when we had our meeting of the Tuesday Dark Runners Club (oh, we're happy as long as we know there is someone else more sad than us out there!) after our 5 mile run, I drug one of the hotties of the opposite sex in the club out for another .7 or so miles. That's always a good sign, when you run a tad more when everyone else is headed in to the bar.
Second sign. I am on a job this summer, no I'm not dry-walling the new McDonald's, I'm watching my buddy Morejon's dogs, and there were three of them. Any way Morejon lives 3.4 miles from my house, if you go the short way. Well I didn't go the short way, and I didn't drive, nor did I take a two-wheeler, I ran, both ways.
That's a great sign, when you start doing errands on foot that you'd normally do in a car, it could mean you go sub whatever in your next race! That's what I'm hoping fer!
It doesn't take an Einstein to read some of these signs.
