In Tokyo Derek achieves something only Ireland’s Robert Heffernan (race walk) and David Wilkins (sailor) have done before – competing in a fifth Summer Olympics. He was 18th in Sydney (2000), 29th in Beijing (2008) and 27th in London 2012 and came agonising close to making the final in Athens 2004 when he shot 119 out of 125 to finish ninth. He missed qualifying for Rio 2016 by the margin of just one target, after being temporarily distracted by the San Marino shooter beside him breaking his gun. Since first competing for Ireland in 1997 the Longford shooter has had three top 10 finishes at World Championships, including 5th in 2002. He has won two World Cup medals (bronze 1998 and silver 2007) and made two European Championship podiums, winning silver in 2010 and 2013. He has achieved the elusive perfect 125 in training but the closest he’s come in competition is 123 at World Cups in Granada (2013) and Tucson (2014). Derek qualified for Tokyo 2020 by shooting 121 in a World Cup event in the United Arab Emirates in 2019.
