As weird as it sounds, extreme ironing tops our list of the Most Extreme Competitions On Earth. Extreme ironing is classed as an 'extreme sport'. The aim of the game is to iron in the most remote, extreme location that you can possibly find. The ironing must be done properly, using an ironing board. The competition describes itself as "the latest danger sport that combines the thrills of an extreme outdoor activity with the satisfaction of a well-pressed shirt."

Extreme ironing is popular not only because of its quirkiness, but the creativity demonstrated by the participants. There are many separate events worldwide, and competition is fierce. Previous entries have featured contestants ironing whilst bungee jumping, ironing underwater, ironing while skydiving and ironing on horseback. Extreme ironing began in 1997 in Leicester, UK, when a man named Phil Shaw decided to iron in his garden. His roommate referred to his antics as "extreme ironing", and the idea was born.
