The team, consisting of Akilah Lewis, Sole Frederick, Sanaa Frederick, and Leah Bertrand, gave it their all but ultimately fell short.
The men’s 4x100m relay saw similar heartbreak for Jamaica. The team, made up of Ackeem Blake, Jelani Walker, Jehlani Gordon, and Kishane Thompson, ran a season-best time of 38.45 seconds but finished fourth in their heat and 11th overall, failing to make it to the finals.

None of these times were sufficient to move on to the semifinals, marking the end of their Olympic campaigns in this event.
