Walking football is a variant of association football that is aimed at keeping people aged over 50 involved with football if, due to a lack of mobility or for other reason, they are not able to play the traditional game. The sport can be played both indoors and outdoors. Walking football was devised, during 2011, by the Chesterfield F.C. Community Trust. Coverage of a session on Sky Sports News led to several other clubs taking up this version of the game. It has since become a current craze.
