New Zealand sprinter Liam Malone has retired from the sport to take up a corporate job.
The 24-year-old won two golds and one silver at the Rio 2016 Paralympic Games but has suffered with injury since, unable to compete at the London 2017 World Para Athletics Championships.
Speaking about his retirement, Malone said: "External events both in and out of my control have taken a toll on my training in the last month and I don't feel I have the emotional investment or necessary focus and energy to succeed at the highest level in Tokyo.
"Becoming an elite athlete was an incredible journey but life is short, I want to find something that I can commit to and be happy in for a long time.
"It would be unjust to commit half-heartedly to those who support me, my coach, the supporting organisations, the New Zealand public, sponsors, my friends and family."
Instead of competing at London 2017, Malone played an integral role in Channel 4's coverage of the 10 days, providing brilliant insight and humour.
He first stole the attention of the British public during the 2016 Paralympics, where he charmed us with his endearing wit and outstanding running.
