Why don't runners say "hi" more often? Anyone who has ever run a race can usually spot a serious runner: the shoes, fancy watch, dri-release clothes, and efficient stride and cadence. Yet I'm amazed how many runners, mostly but not exclusively female, refuse to gaze in my direction when we cross paths. Of course, caution is necessary. I understand the safety issues. But come on, we're not on the mean streets of New York or Detroit, and I don't run at night. Some runners make some kind of gesture of acknowledgement and I appreciate that. But why not more? We're a brother and sisterhood of athletes...it's not that scary!
