Smyth is now a six-time Paralympic champion. He won the T13 100m and 200m at both 2008 Games in Beijing and the 2012 Games in London, and the 100m five years ago in Rio.
The Derryman is also the fastest Paralympian of all-time, holding the World and Paralympic records in T13 100m (10:46) and 200m (21.05), which he set at the London Paralympics in 2012.
Smyth competes in T13 category because he has Stargardt’s disease, which affects his central vision.
