Context: Isobel Pooley (born 21 December 1992) is a British track and field athlete who specialises in the high jump.  She won a silver medal at the 2014 Commonwealth Games in Glasgow.  Three weeks later on 24 August 2014, she cleared 1.96 m to break the 32-year-old UK outdoor high jump record.  She went on to jump 1.97m in The National Championships at Alexandra Stadium in Birmingham on 4 July 2015. Montserrat competed in their third Commonwealth Games in 2002.  Only one athlete took part, Gavin Lee who competed in the Men's High Jump and jumped 1.95 meters, finishing 16th. Helen Audrey Ray Frith (born July 12, 1939 in Roseville, New South Wales, Australia) is an Australian athlete.  She competed in the 1960 and 1964 Olympics, representing her native country in the long jump, high jump and pentathlon.  She won silver medals at the 1962 British Empire and Commonwealth Games in both the long jump and high jump.  She is the daughter of masters athletics legend Ruth Frith who also coached her.  She joined her mother in masters competition, under her married name Helen Searle she holds masters W60 world records in the hammer throw and throws pentathlon. John Vernon (born 3 September 1929) is an Australian former high jumper who competed in the 1956 Summer Olympics.  He finished seventh in the 1950 British Empire Games high jump.

Burke attended University College Dublin on an athletics scholarship and also studied at the University of Limerick.  He had an eclectic athletic career representing Ireland as a senior athlete at the high jump, long jump, 400 metres and 400 metre hurdles.  He was runner up at the 1994 World Junior Championship in the high jump and four years later jumped a personal best of 2.24 metres.  Burke never subsequently met the expectations set by his silver medal but competed for some number of years both in the high jump and other events.  Whilst some observers of Irish athletics mused that 6 ft 4 tall Burke who was in and around fourteen stone could have fond his ultimate forte as a decathlete he was a surprisingly poor and unathletic thrower making success in this field quite uncertain. Tania Dixon (née Murray) is a high jumper and triple jumper from Dunedin, New Zealand.  Murray won the gold medal in the women's high jump at the 1990 Commonwealth Games in Auckland.  In 1991, she set a New Zealand record for the women's high jump of 1.92 metres, and in 1997 set a similar record for the triple jump of 13.48 metres.  Murray was New Zealand women's high jump champion in 1988, 1990, 1991, 1992, and 1997, and was New Zealand triple jump champion in 1994, 1997, and 1999. Robyn Woodhouse (born 26 July 1943) is a former female track and field athlete from Australia, who mainly competed in the high jump event during her career.

Debbie Arden Brill, {'1': ", '2': ", '3': ", '4': "} (born March 10, 1953) is a Canadian high jump athlete who at the age of 16 became the first North American woman to clear 6 feet.  Her unique reverse jumping style—which is now almost exclusively the technique of elite high jumpers—was called the "Brill Bend" and was developed by her when she was a child, around the same time as Dick Fosbury was developing the similar Fosbury Flop in the USA.  Brill won gold in the high jump at the 1970 Commonwealth Games, and at the Pan American Games in 1971.  She finished 8th in the 1972 Summer Olympics, then quit the sport in the wake of the Munich massacre, returning three years later.  She won gold at the IAAF World Cup in 1979, and at the 1982 Commonwealth Games.
