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

Train at the same pace day after day, week after week, year after year, and that's the kind of running the body adapts to. But break out of that comfort zone with a little speedwork now and then, and the body will learn to deal with the new demands.

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.

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.

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.

The key to running a good marathon is to not listen to anyone's advice the last week before the race. That's when people tend to do stupid things that disrupt all the input and training of the previous months.
