On 6 May 1954, he acted as pacemaker for Roger Bannister when the latter ran the first sub-four-minute mile at Iffley Road Stadium in Oxford. Brasher paced Bannister for the first two laps, while his friend Chris Chataway paced the third. Two years later, at the 1956 Summer Olympics in Melbourne, Brasher finished first in the 3,000 metressteeplechase with a time of 8 minutes 41.2 seconds, but was disqualified for allegedly interfering with another runner, Ernst Larsen of Norway. The following day, after an investigation, he was reinstated as gold medallist. Brasher had been celebrating for several hours before the delayed medal ceremony, and later claimed to have been “the only Olympic champion to be totally and absolutely slaughtered when he received a medal”. He was one of the pioneers of orienteering in Britain and can claim the first public mention of the sport in an article in The Observer in 1957:
Later career
He had distinguished careers in print journalism, as sports editor for The Observer newspaper, and in broadcasting, as a reporter for the Tonight programme. He founded Chris Brasher's Sporting Emporium in 1971; this later became Sweatshop. In 1978, he designed the innovative Brasher Boot – a walking boot with the comfort of a running shoe. In their time these were amongst the best products, but declined in quality, were merged with Berghaus under Pentland ownership in 2014, and were finally discontinued before 2017. In 1981 John Disley and Brasher founded the London Marathon. In 1983 he became the second president of the Association of International Marathons and Distance Races, an office which he held until 1987. Also in 1983 Brasher partnered with his longtime friend John Disley to found Fleetfoot Limited in Lancaster, England. Fleetfoot distributed The Brasher Boot and other sporting goods to retailers. Fleetfoot acquired the rights to be the UK distributor of Reebok and subsequently traded as Reebok UK before becoming a subsidiary of the Pentland Group in 1988. After the acquisition by Pentland, Brasher remained active in the company as chairman of the board. Reebok UK was sold to Reebok International in 1990 when Pentland Group sold its 55% ownership of Reebok United States and Reebok International.
Brasher was married to tennis champion Shirley Brasher née Bloomer. Brasher was awarded the CBE in 1996. He was awarded the Royal Scottish Geographical Society's Livingstone Medal in 2002. In 2003, he died at his home in Chaddleworth, Berkshire, after struggling for several months against pancreatic cancer.
