Gentle art of running about a quarter of the distance you're supposed to by ducking into a graveyard and waiting for the runners to come round again. Under no circumstances should one recommence as the leaders come through, therefore breaking ones personal best by about ten minutes and getting thrust into the school team, only to embarass yourself when trailing in last by a huge margin at an inter-school event.

Sage advice, and sadly not heeded by one J.C. Royston in his efforts to skive the once-yearly school run. His effort consisted of ducking under a bridge approx 200m from the start/finish line, and treating himself to a crafty kip.
On waking, he peeked out, troll-like, from under the bridge, and saw the finish line was absolutely deserted of everyone bar the timekeepers. Coming to the natural conclusion that everybody else must have finished, he came out from his hiding place and put in an impressive sprint finish.
On crossing the line, however, he was informed by a (curiously unimpressed) teacher that he had just knocked 28 minutes off the previous school record of 44 minutes.
J.C. Royston was not promoted to the school team on the basis of this superhuman feat; he was put into detention, where he presumably had to write out "I must not run at twenty five miles per hour" a thousand times.
