Athletics - Team United States of America

General
No other nation has contested the men's 4x100m relay at as many Olympic Games or won as many Olympic medals in the event as the United States of America. In 23 appearances since their debut at the 1912 Games, the US team has won 17 medals, including 15 golds. Only three other nations - Great Britain, Jamaica and the Soviet Union - have won more than one gold, with all three on two each.

The US team dominated the event throughout the 20th century, winning gold at eight consecutive Games from 1920 to 1956, until a disqualification in the final at the 1960 Games ended their streak. They bounced back to win another four consecutive golds from 1964 to 1976, but towards the turn of the 21st century and beyond their dominance has waned, in part due to failures to post an official result. They did not contest the 1980 Games due to their boycott against the Soviet Union, and as reigning world champions and favourites to win gold at the 1988 Games they were disqualified from their heat in Seoul. At the 2008 Games they were also reigning world champions, but a dropped baton saw them fail to progress from the heats. In 1996 and 2004, however, they were simply beaten to gold by Canada and Great Britain, respectively.

In recent years, the team courted controversy with the disqualification of their 2012 Olympic silver medal due to Tyson Gay's anti-doping violation. At the 2016 Games, despite crossing the line in third in the final, they were disqualified for passing the baton outside the takeover zone.

At the world championships the US team are equally dominant, with eight gold medals compared to their nearest rivals Jamaica on four. They claimed their first title at the tournament in 12 years at the 2019 edition in Doha, finishing 0.26s ahead of Great Britain.
