Aries Merritt

He won the 2017 IAAF Diamond League 110m hurdles in Rome on June 8, 2017

Merritt finished 6th in 2013 World Championships in Athletics – Men's 110 metres hurdles. After the competition, he felt very ill and was diagnosed with collapsing focal segmental glomerulosclerosis, a rare congenital kidney disease, aggravated by a parvovirus that had attacked his kidneys and bone marrow. After several months of medical treatment, he was eventually able to return to competition on the following year, albeit far from his previous registers.

Merritt began the 2012 campaign by altering his approach to the first hurdle, switching from eight to seven steps. In an interview he stated, "[it] was pretty risky to make a change like that, but something had to be done if I was going to compete with (Liu Xiang of China and Dayron Robles of Cuba). The change allows me to maintain my momentum going into the first barrier." Merrit's change was highly successful for the 2012 indoor season as he became the indoor world champion in the 60 meters hurdles at the 2012 World Indoor Championships in Istanbul. In the final, he beat Liu Xiang and Pascal Martinot-Lagarde with a time of 7.44 s.

At the 2012 Olympic Games in London, Merritt began by running the fastest qualifying time in the heats with a time of 13.07 s. In the semi-finals, he was again dominant with a time of 12.94 s. In the final, Dayron Robles and Merritt got the fastest starts but Merritt pulled ahead at hurdle 3. He continued to a personal best of 12.92 s and a 0.12 s win over reigning world champion Jason Richardson.

On September 7, 2012, at the final Diamond League meet (Memorial Van Damme) in Brussels, Belgium, Merritt ran a time of 12.80 s in the 110 meter hurdles, shattering the old world record of 12.87 s held by Dayron Robles. Merritt's performance was the largest drop in the world record for 110 meter hurdles (0.07 s) since Nehemiah in 1981. Merrit ran consistently throughout the 2012 season. The following are his times that lead-up to his world record performance in the 110 meter hurdles:

In the final of the 110m hurdles at the 2011 World Championships in Athletics, Merritt was initially classified 6th, with a time of 13.67 s. After Dayron Robles was disqualified, Merritt was promoted to 5th. His season's best was 13.12 s, achieved in Eugene, Oregon and Oslo.

Born in Chicago, Illinois, he moved to Marietta, Georgia at a young age, attending Joseph Wheeler High School, where he was teammates with Reggie Witherspoon. Merritt ran for the University of Tennessee from 2003 to 2006 and had a successful college career, a seven-time All-American. He took the 110 meter hurdles gold at the 2004 World Junior Championships and finished sixth at the 2006 World Athletics Final. Also in 2006, he won the NCAA Championships, Indoors and Outdoors and was undefeated in all hurdles events that year. He broke Willie Gault's Tennessee Volunteers hurdles record. His victory at the NCAA Championships in 13.21 s was the second fastest ever collegiate time in the United States, behind only Renaldo Nehemiah. He reached the World Athletics Final in 2008, finishing in fourth. Merritt is the first hurdler to ever win gold in the US Indoor Championship, the World Indoor Championship (Istanbul, Turkey), the US Olympic Trials, and the Olympic Games all in the same year.
