List of ISH Showjumpers: The Irish Sport Horse (ISH) (US: Irish Draught Sports Horse), also known as the Irish Hunter, is mainly the result of a cross between the Irish Draught and the Thoroughbred.  It has been given recognition as a separate breed.  It is commonly bred from parents who are also Irish Sport Horses, in addition to being bred from the definitive parent breeds.  The Irish Sport Horse is traditionally used for all purposes, from transportation, to riding, and working the land.  However, it is becoming increasingly popular as a competition riding horse.  Its athletic ability and jumping talents means that it does well in the show jumping arena, as well as competing at the highest levels of eventing.  The horse is renowned for being one of the best fox hunting mounts in the world, and the Irish Sport Horse studbook regularly tops the rankings for eventing.  Ireland produces a largr number of Irish Sport Horses each year, many of them selling for large amounts in the United States and Europe.

Wayne Grimditch: Wayne Grimditch (b. 1955?)  is a Hall of Fame water skier.  He competed for the United States in the 1972 Summer Olympics in Germany, winning two silver medals in the water skiing (though as water skiing was a demonstration sport in 1972, they are not included in the medal tables).  Grimditch would go on to establish 10 U.S. national jumping records and four world marks in the sport.  He earned 16 national titles and was the first skier to earn jumping records in the Junior Boy's, Boy's and Men's divisions simultaneously.  Grimditch was known as a child prodigy qualifying for his first national tournament in slalom at just nine years old and winning the world jumping title in Copenhagen, Denmark at age 14.  Due to a concussion, he began wearing a helmet which became common to the sport—though not a requirement—thereafter.  Perhaps most notable among his world records is the one for longest ski jump, breaking his thrice-held previous records by jumping 180 feet in the air in 1975.

Rock hopping: Rock Hopping is an activity involving jumping off rocks.  Some variations of this activity may involve jumping off a cliff into a body of water such as a river or lake.  It is also known as cliff jumping or <nowiki>"quarry jumping"</nowiki>, since abandoned, water-filled quarry holes are popular for this activity, featuring steep, tall cliff faces and deep water.  Rock hopping can be used as a means of getting from one place to another in combination with scrambling over rocks for the purpose of outdoor activity such as rock climbing.  It has also become an extreme sport whereby participants jump over large gaps, sometimes without any form of safety device such as a securing rope to ensure they do not fall and injure themselves or worse.  It can also refer to traveling up a boulder-filled stream or brook by jumping from rock to rock, while avoiding falling in.

BASE jumping: BASE jumping, also sometimes written as B.A.S.E. jumping, is parachuting or wingsuit flying from a fixed structure or cliff.

In some jurisdictions or locations, BASE jumping is prohibited or illegal; in some places, however, it is permitted, like Perrine Bridge, in Twin Falls, Idaho, United States.  BASE jumping became known to the wider public by depictions of BASE jumping in a number of action movies and was featured in the 2014 documentary "Sunshine Superman".
