Rhydian Cowley made his international debut in the junior event at the 2008 World Walking Cup in Russia, following up with another World Walking Cup and the IAAF World Junior Championships in 2010.
He made his senior debut in 2012, competing at the World Race Walking Cup aged just 21, and then the following year lined up at the 2013 IAAF World Championships in Moscow.
There were further team starts in 2014 (World Walking Cup) and 2015 (Summer Universiade). Rhydian was unfortunate to miss selection for the 2015 IAAF World Championships in Beijing as the fourth fastest qualified athlete but bounced back the following year to make his Olympic debut in 2016 in Rio where he placed 33rd in 1:23.30. Selected for the 2017 IAAF World Championships, he placed 56th in the 20km walk in 1:30.40.
In February 2018 at the Australian Championships 20km walk in Adelaide, he placed tenth, but importantly as the third Australian Rhydian secured Commonwealth Games selection.
After being encouraged to get into Little Athletics by his dad, Rhydian started race walking when he was eight. He is coached by former 50km walk world champion, Simon Baker and has completed a Bachelor of Arts/ Bachelor of Commerce, Deakin University (2009-2014).
