Quanera Hayes, Allyson Felix, Shakima Wimbley and Phyllis Francis won by the largest margin of victory in world championships history – male or female – to capture the first Team USA gold medal in the event since 2011. The United States won silver medals in 2013 and 2015.
Hayes ran the first leg for Team USA.
The ladies finished with a time of 3 minutes, 19.02 seconds, followed by Great Britain in 3:25.00 and Poland in 3:25.41 Sunday night at London Stadium.
That translated to a distance of about 50 meters.
The previous greatest margin of victory for the women’s relay was Team USA over Jamaica in 2009 (3.32 seconds) and for the men’s relay was Team USA over Kenya in 1993 (5.53 seconds).
