1. No balls or sticks. No one hits or throws anything. Here the action centers on people, not objects. 2. No timeouts. Once a race starts, it doesn't stop for commercials or any other excuse. 3. No overtime. A race ends at its finish line, with no one ever asked to go the extra mile to settle a score. 4. No scoring. Racing results aren't figured by points but are a simple matter of time. 5. No substitutions. A weary runner can't call for relief, and an eager but less talented one doesn't have to warm the bench. 6. No cuts. Runners are never told to clean out their lockers and not to come back because they aren't good enough. 7. No teams. There's no one to hold you back when you're running well, and no one to carry you when you're doing poorly. 8. No sex-separation. In football and baseball the men play and the women cheer. In running they all race at once. 9. No referees. At least none in striped shirts who can blow a whistle during a race and assess a penalty on the spot. 10. No rules. At least none more complicated than filing an entry, starting at a scheduled time and place, and staying on the course for the full distance. 11. No fighting. When was the last time you saw two runners stop in midrace and settle an argument with their fists? 12. No stadiums. Spectators don't sit in box seats. They stand beside the streets. 13. No ticket sales. Spectators don't pay to watch the runners. Runners pay to entertain the fans. 14. No crowds. Boston and New York City Marathons aside, rare is the road race where the fans outnumber the runners. 15. No booing. People who watch our sport from the sidelines don't act on the urge to verbally abuse a runner they don't like. 16. No betting. Las Vegas publishes no "line" on our events, and no office pools ride on the results. 17. No off-season. We never have to wait six months for the races to start again; there's always one next week, somewhere. 18. No one winner. When winning means meeting personal standards, a race has as many potential winners as it has entrants. 19. No clear losers. When losing means falling short of personal standards, the first finisher can "lose" and the last one can "win." 20. No retirement. Runners never need to quit as they grow older and slower, and rarely do. They can always feel young again within a few years by graduating into a new age-group.
