Mark Anthony Lewis-Francis, MBE (born 4 September 1982) is a retired British track and field athlete, specifically a sprinter, who specialised in the 100 metres and was an accomplished regular of GB 4 x 100m relay. A renowned junior, his greatest sporting achievement at senior level has been to anchor the Great Britain and Northern Ireland 4 x 100 metres relay team to a gold medal at the 2004 Summer Olympics. Individually, Lewis-Francis has won the silver medal in the 100 m at the 2010 European Athletics Championships and silver medal in the 2010 Commonwealth Games, Men's 100m final and numerous indoor medals. Lewis-Francis is a member of the Birchfield Harriers athletics club and is also known as the "Darlaston Dart". Early career Lewis-Francis burst onto the scene at an early age but did not attend the 2000 Summer Olympics, instead competing at the World Junior Championships, in which he won gold. Lewis-Francis became Britain's top 100 m sprinter after Dwain Chambers was banned for drug use in 2003. He failed to make the final of the 100 m at the 2004 Summer Olympics, but days later ran the final leg of the 4 × 100 m relay, famously holding off former Olympic champion and world record holder Maurice Greene, allowing the Great Britain team to narrowly win in a time of 38.07 seconds. The gold medal team consisted of Lewis-Francis, Marlon Devonish, Darren Campbell and Jason Gardener. As the last of the four in both race and alphabetical order, Lewis-Francis became the fiftieth man to win a gold medal for Great Britain in Athletics at the Olympics. Despite this and other Olympic and World relay success, his junior success has not as yet translated to consistent performance at the highest level in individual championships. His surprise silver medal in the 100m at the 2010 European Athletics Championships was his first individual medal at senior level. Transition to seniors In 2001 Lewis-Francis won a World Athletics Championships 100 m quarter-final heat in 9.97 seconds, which would have been a junior world record, but a wind gauge malfunction meant it was unratifiable. Unusually, Lewis-Francis' times have become slower as he has moved into his twenties. Although athletes tend to peak around their late 20s in the sprints, Lewis-Francis peak to date remains his performances while in his late teens. He has turned down numerous invitations to train with the top sprinters
