Jamaica was the only Caribbean team to secure a lane in the final of the 4x400m Mixed Relay as they were dragged in qualifying by United States, which registered the first World Record of the Paris Olympic Games at the Stade de France on Friday.

Running from lane six in heat one, the Americans—Vernon Norwood, Shamier Little, Bryce Deadmon, and Kaylyn Brown—left the field in their wake to stop the clock in 3:07.41, bettering their own previous mark of 3:08.80 set at last year’s World Championships in Budapest. Poland’s Olympic Record of 3:09.87 set in Tokyo, was also erased.

France (3:10.60) and Belgium (3:10.74) were second and third with national record times, while Jamaica’s quartet of Raheem Hayles, Junelle Bromfield, Zandrion Barnes, and Stephanie-Ann McPherson also clocked a national record of 3:11.66 for fourth. They progressed as one of the fastest non-automatic qualifiers, along with Poland (3:11.43).

Bahamas struggled throughout and ended at the back of the pack in 3:14.58. The same is true about Dominican Republic (3:18.89) in heat two.

That heat was won by Great Britain in a national record 3:10.61, ahead of Netherlands (3:10.81) and Italy (3:11.59).
