Jesse Owens's greatest achievement came in a span of 45 minutes on May 25, 1935, during the Big Ten meet at Ferry Field in Ann Arbor, Michigan, where he set three world records and tied a fourth. He equaled the world record for the 100 yard dash (9.4 seconds); and set world records in the long jump (26 ft 8 1⁄4 in or 8.13 m, a world record that would last 25 years); 220-yard (201.2 m) sprint (20.3 seconds); and 220-yard (201.2m) low hurdles (22.6 seconds, becoming the first to break 23 seconds). In 2005, University of Central Florida professor of sports history Richard C. Crepeau chose these wins on one day as the most impressive athletic achievement since 1850.

His achievement of setting three world records and tying another in less than an hour at the 1935 Big Ten track meet has been called "the greatest 45 minutes ever in sports."
