Thank you all for entering the matinee jacket giveaway, it's great to get such high participation! And what a huge range of guesses, from 54m all the way up to 390m! Yikes!!
Here is the correct answer in relation to an average sized football pitch:
Yep, that's right. I rolled a big roll of paper down the length of a football pitch and a quarter of the way back up again, crouching and kneeling my way along, eyes six inches above the paper, arm crooked, shuffling around and writing on each piece. At least the renumeration will contribute to an orthopaedic surgeon should my knees and back not recover. The exact answer? 117m!
Hmmm... does that number sound familiar? By some feat of advanced mathematics or (as I suspect) witchcraft, Nickynackynoo got exactly the right answer. Well done Nicky and thanks again to everyone who participated!
