Welly throwing, also known as welly hoying, welly wanging and boot throwing, is a sport in which competitors are required to throw a Wellington boot as far as possible. The sport appears to have originated in the West Country of England in the 1970s, and rapidly became a popular activity at village fêtes and fundraising events across Britain. The sport is now played in many different countries, including Australia, Estonia, Finland, Germany, Ireland, Italy, New Zealand and Russia.
Depending on local custom, different rules are applied to the sport. In parts of Somerset, for example, the boot is filled with water before being thrown. Some competitions allow a run up before releasing the boot, while others require the throw to be made from a standing position—which may be enforced by making the thrower stand in an empty dustbin. In Welbury, North Yorkshire, the size of the boot thrown must be large enough to comfortably fit the thrower. Other competitions specify the size of the boot and the manufacturer.
A number of associations have been formed to govern the sport, including the International Boot Throwing Association (based in Helsinki, Finland), the World Welly Wanging Association (Upperthong, UK), the World Welly Throwing Association (Settle, UK), the World Wellington Boot Throwing Association (Wellington, UK) and the New Zealand Boot Throwing Association (Taihape, New Zealand).
The first world record throw recognised by Guinness World Records was 52.73 metres (173.0 ft), set by Tony Rodgers in Wiltshire, UK, in 1978, using a size 8 Dunlop "Challenger" boot. The current world records are 63.98 metres (209.9 ft) for men, set by Teppo Luoma (Finland, 1996), and 40.87 metres (134.1 ft) for women, set by Sari Tirkkon (Finland, 1996).
