Born in Sutton Coldfield, Birmingham, Jonathan Moore began practising triple jump at the age of thirteen. His first medal came at the English Schools' event in 1999 and he won gold at the same event in 2000. In 2000 he also won the U17 Championships in both events and the Schools' International and Commonwealth Youth Games in the triple jump. That year he became the first under 17-year-old to clear 16 metres in the triple jump.Rowbottom, Mike (2002-01-10). . The Independent. Retrieved on 2009-01-28.
