Crackle, hiss, squeak, whine -- and they're off. Six Reception kids zig zagging down the track, uncertain where to head for or what to do when they get there.

One memorable year the behaviour policy decreed that too much competition was detrimental to an individual's self-worth. Thus, the standard sports day format was replaced by a sports "carousel".

Everyone seems to cope better, especially the dads.
The parent-teachers' association, as always, provides first-class refreshments. For months no supermarket has been safe: any special offers are snapped up, freezers left empty, soft drinks sections laid bare.
