One of life's simplest pleasures is going for a run outside. The late Dr. George Sheehan summed it up best: 'Out on the roads there is fitness and self-discovery and the persons we were destined to be.' So once in a while let's forget about footwear, performance standards, and high-tech gadgetry -- and instead simply let your body and imagination take you to new and familiar places. Armed with a sense of play as you run, there is no purpose or outcome other than to escape and be in the moment.
