In those long, lonely miles you put in during the off-season, and in those knife-in-the-gut repetitions and hill repeats that buckly your knees - at that moment in almost every race when you ask yourself how much you're willing to hurt to catch one more runner - you can draw strength and inspiration from your running mates.

There's no such thing as a bad carbohydrate.

Without ice cream there would be darkness and chaos.

Avoid any diet that discourages the use of hot fudge.

A good teammate is someone willing to get outside of personal thoughts and emotions, a friend who tries to understand, appreciate, and encourage other members of the team.

Eventually, competition and adventure wane, and I enter my ibuprofen phase. Tweaky hamstrings and achy knees restrict mileage, but I continue running for health, sanity, and the ritual of a Sunday trail run with like-minded buddies. We discuss the nagging injuries that bedevil us, and remember the good old days when we were kings.

So here's my advice to city planners. Make your city runnable. Runners are the first wave of troops bringing human activity back to the urban core of any city. Where we go, others will follow. The connection between runnability and livability is so clear (at least to me), that it's surprising that new developments consistently leave pathways out of the plans.
