Back in the late 70s or early 80s, some young thruster ordained that all aircrew of a certain large aeroplane squadron based not far from Burford were to complete X laps of the sports field.
Having first elicited what a sports field was and, more importantly, where it was, the old gents duly turned up. Complete with overcoats, dogs, walking sticks, the odd hip flask and pipe of tobacco. Then strolled at a leisurely pace, as befits a gentleman, for the requisite number of laps. It took all morning, but the thrusting racing snake who had come up with the idea had to stand and shiver in his jockstrapping kit whilst the old buggers slowly strolled about. "Come on chaps, let's run for a bit" was duly greeted with looks of astonishment and "Dear me, what an appalling notion. How very undignified!"
