100 metres Backstroke, Men

Date	29 – 30 July 2012
Status	Olympic
Location	London Aquatics Centre, Olympic Park, Stratford, London
Participants	43 from 33 countries

Aaron Peirsol had won the last two gold medals in this event but had retired, so the event seemed much more open. The 2011 World Championship had ended in a tie between two Frenchmen, Camille Lacourt and Jérémy Stravius. Including Peirsol, the last four titles in this event had been won by Americans who were led in London by Matt Grevers, the 2008 silver medalist behind Peirsol.

The final turned into a battle between Lacourt and Grevers with Lacourt leading at the turn in 25.31, actually ahead of Peirsol’s world-record split, but he could not maintain that pace and Grevers came on strong to win in an Olympic record 52.16, the fastest ever textile time. It was the fifth straight gold medal for the United States in the event and came only a few minutes after Missy Franklin had won the women’s 100 back. Lacourt fell apart in the closing metres of the race, dropping off the podium to fourth place, as the silver went to American Nick Thoman in 52.92, with Japan’s Ryosuke Irie winning bronze in 52.97.
