Wholeheartedly agree. Anyone who's taken time out to do a spot of marshalling will know that numbers on shorts are never mounted in a central position. They show to one side. EG if your number is on the left leg of your shorts, that's ideal for marshals stood on the LHS of a trod/path, but a total ball-ache for marshals stood on the RHS of the path, and vice-versa; unless of course, these fairy-brained individuals are prepared to deviate from the path and pass the marshalling point so that their individualism displays clearly to the marshals. Even worse are the idiots crossing over to fell running from trail and adventure racing, who pin their numbers to their bumbag / ruc-sac. At somewhere like CP1 ( Causey Pike ) on the TWA, it's a full time job taking numbers of those popping up over the crag as they approach you; without having to turn around and attempt to read numbers on the bumbags of those descending away from you.
