John was inspired to get into archery by London 2012 after watching American Sports star Matt Stutzman competing. In 2013, he took up the sport as a hobby.
His talent for the sport soon began to show, and after he was first selected to join the GB Para squad in 2014 he went on to shoot two European records and four world records.
After a rapid rise through the ranks, John made his Paralympic debut at Rio 2016. He won gold in both of his events, the men's individual compound (W1) and the mixed team compound (W1), where he competed alongside team-mate Jo Frith.
The pair excelled in their key matches to reach the top of the podium, winning against the Czech Republic and defeating the Republic of Korea in the gold medal match.
In his individual event, John showed solid form through the knockout rounds before beating David Dramoninsky of the Czech Republic in a closely-fought final.
Away from the Paralympic stage, career highlights include individual silver and mixed team gold at the 2015 Para World Championships in Donauschingen, Germany and mixed team gold at the 2016 European Para Championships in Saint Jean De Monts, France.
