Pity the out-of-shape runner. He slogs along, willing himself not to stop, not to give up hope, not to collapse. What does he get for it? Firmer calves, perhaps, but certainly embarrassment, should anyone he knows see him. For such a runner, the perfect course must be short (so he can complete it), shaded (so he won't melt from heatstroke), and hidden (so he'll avoid the ridicule of his peers). The Bonne Bell running track in Westlake fits all those criteria: It's short -- there are one-mile and two-mile loops -- almost entirely wooded, and blissfully quiet.
