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.

Prior to the 1976 Olympics, I was a 5,000m runner.

If you run 100 miles a week, you can eat anything you want - Why? Because (a) you'll burn all the calories you consume, (b) you deserve it, and (c) you'll be injured soon and back on a restricted diet anyway.

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.

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.

I know runners who have suffered a tick bite and ended up with Lyme disease. Ill take an angry moose any day.
