10.11 and then ran a time of 10.08 in the final. That time was the second fastest 100 m ever run by a British Junior, behind only Dwain Chambers (10.06 sec). At the time of his victory, James Dasaolu was the only one other British athlete to have met the Olympic qualifying time for the men's 100 m. Gemili was selected for the British 2012 Olympic 4 × 100 m relay team on 3 July 2012. On 11 July 2012, Gemili finished first in the 100 m at the 2012 World Junior Championships in Athletics, winning the gold medal in a time of 10.05 seconds, breaking the championship record originally established by Darrel Brown in 2002. Besides breaking the British national junior record, Gemili's 10.05 ranks sixth all-time among juniors, behind only Brown, Jeffery Demps, Marcus Rowland, D'Angelo Cherry and Christophe Lemaitre. He ran 10.11 in his first heat in the 100 m at the London 2012 Olympics, finishing second behind Asafa Powell. As he finished in the top three of the heat Gemili qualified for the next round but despite finishing third in his semi-final in a time of 10.06, he failed to make the final. He qualified for the 2013 World Athletics Championships in Moscow for the 200 m. In his semi-final, he clocked a time of 19.98, the second fastest time ever by a Briton in that distance, having been bettered only by John Regis. He thus qualified for his first major final and finished 5th with a time of 20.08. At the 2014 Commonwealth Games on 28 July 2014, Gemili finished second in a time of 10.10 seconds in the Men's 100 m final in a race won by Kemar Bailey-Cole of Jamaica. 2015-19 On 31 May 2015, he broke the 10-second barrier in the 100 m for the first time in his career, with a run of 9.97 seconds; however, the wind speed (+3.7 m/s) was above the legal wind limit. On 7 July 2015, at the IAAF Diamond League meeting in Birmingham, he became the 100th man in history to break the 10-second barrier legally in the 100 m, again clocking 9.97 seconds (+2.0 m/s); however, he fell as he crossed the line, picking up a hamstring injury which would cause him to miss the 2015 World Championships. He is the one hundredth man to break 10 seconds. Gemili qualified for the Men's 200
