High diving is the act of diving into water from relatively great heights. High diving can be performed as an adventure sport (as with cliff diving), as a performance stunt (as with many records attempts), or competitively during sporting events. It debuted as a sport at the 2013 World Aquatics Championships in Barcelona.In the world championships, men jump from a 27-metre-high (89 ft) platform while women jump from a 20-metre-high (66 ft) platform. In other official competitions, men generally dive from a height of 22–27 metres (72–89 ft) while women dive from a height of 18–23 metres (59–75 ft). The sport is unique in that athletes are often unable to practice in an authentic environment until the days leading up to a competition. High diving has been designated a sport separate from regular diving by FINA. High divers have achieved speeds of descent of 96 kilometres per hour (60 mph).
