}} Callum Priestley (born 13 February 1989) is a British former track and field athlete who specialised in sprint hurdling. He was banned after a positive sample for banned substances was found in a urine sample whilst training with the UK team in South Africa in January 2010. Subsequent to the ban, Priestley retired from competitive athletics. He began competing in athletics while at school and finished second in the 110 metres hurdles at the 2005 English Schools' Athletic Association Championships. Progressing through the ranks at youth level, he represented Great Britain at the 2007 European Athletics Junior Championships and reached the hurdles final, although he did not finish the race.〔(Callum Priestley Profile ).
