Reid, from Alexandria in West Dunbartonshire, started playing wheelchair tennis in 2005 after contracting transverse myelitis shortly before his 13th birthday.
He made his Paralympic Games debut in Beijing in 2008 before making history at Rio 2016, becoming ParalympicsGB’s first ever men’s singles gold medallist after beating Alfie Hewett in the all-British final. He also partnered Hewett to win silver in the men’s doubles.
