Shin-kicking (also known as hacking or purring) is an ancient sport, part of the annual Cotswold Olimpicks. The aim of shin kicking are simple: kick your opponent as hard as you can in the shins. Each time your opponent falls to the ground you earn a point.
The winner is the person with the highest score in the best of three rounds. Competitors face each other and hold onto each other's collar. They kick at each others shins to try and knock them down.
They can also pad their legs with as much straw as possible, and thankfully are required to wear soft shoes. No more steel capped boots like in the past!
