Breakdancing is the latest obscure sport to be submitted for consideration at an Olympic Games and could feature in Tokyo 2020 if approved. Surfing, baseball, skateboarding and sport climbing are just a few of the new arrivals set to debut in 2020, but there have been even weirder sports contested in previous competitions.
Underwater swimming featured at the 1900 Olympic Games in Paris and was won by Frenchman Charles de Vendeville, who swam 60 metres to beat a field of 13 other contenders. The horse long jump also made its first and only appearance as an event at the 1900 Games.
Water motorsports failed to impress at the 1908 Games in London and never featured again, the same number of times live pigeon shooting was part of the programme (1900).
