Dylan Armstrong made his Olympic debut at Beijing 2008 where he finished fourth, missing out on a medal by just one centimetre. In June 2013 bronze medallist Andrei Mikhnevich of Belarus was banned for life following a re-test of his doping sample from the 2005 IAAF World Championships. Although not yet made official by the IOC, the retroactive disqualification of Mikhnevich puts Armstrong in line to receive the Beijing bronze medal. Armstrong has already been upgraded to the bronze medal from his original fourth place finish at the 2010 IAAF World Indoor Championships.
Armstrong went on to finish in the top-five for a second straight Olympic Games at London 2012.
The Kamloops, BC native is a two-time outdoor IAAF World Championship medallist, winning silver in 2011 and bronze in 2013. He is the first Canadian to ever win a world championship medal in a throwing event.
A two-time Pan American Games gold medallist (2007, 2011) and the 2010 Commonwealth Games champion, Armstrong won the overall title in shot put for the 2011 Diamond League.
Armstrong set a Canadian outdoor shot put record of 22.21m in June 2011.
Armstrong is coached by Dr. Anatoliy Bondarchuk, a two-time Olympic medallist in hammer throw for the Soviet Union in 1972 and 1976.
