Jamaica Breaks 40-Second Barrier in Mixed Sprint Relay

Jamaica just made history that seemed impossible minutes earlier.

At the World Relays in Gaborone, Botswana, the Jamaican sprint team blazed through the mixed 4x100m relay in 39.99 seconds on Saturday. They became the first team ever to break the 40-second barrier in the event, which features two men and two women running together.

The record-breaking squad of Ackeem Blake, Tina Clayton, Kadrian Goldson, and Tia Clayton didn't just edge past the milestone. They smashed it by nearly a tenth of a second, and they did it in a qualifying heat where teams typically save energy for finals.

What makes the moment even more remarkable is its timing. Canada had set a world record of 40.07 just minutes before Jamaica took the track. The mixed 4x100m is still brand new to global competition, having made its debut at the 2025 World Relays with a best time of 40.30.

The United States also had a strong showing at the two-day event, qualifying for three relay events at the 2027 World Track and Field Championships in Beijing. Team USA advanced by finishing in the top two of their heats in both the men's and mixed 4x100m, plus the mixed 4x400m.

The American squad features impressive talent, including 2025 U.S. 100m silver medalist Courtney Lindsey and Tokyo Olympian Ronnie Baker. They'll compete in Sunday's finals, which stream live on Peacock at 8:02 a.m. ET.

Jamaica brought Olympic firepower with gold medalists Elaine Thompson-Herah and Shericka Jackson on their roster. Host nation Botswana countered with their own stars, including Olympic 200m champion Letsile Tebogo and world 400m winner Collen Kebinatshipi.

Why This Inspires

The mixed relay represents something beautifully simple in sports: men and women competing side by side as true teammates. Unlike separate events where genders compete apart, this format showcases collaborative athleticism at its finest.

The event's rapid evolution shows how quickly athletes can push boundaries when given new challenges. What seemed like a solid record one year becomes a barrier to break the next, then gets obliterated by nearly half a second in another year.

Track fans have something special to anticipate. The mixed 4x100m makes its World Championships debut in 2027 before taking center stage at the LA28 Olympics, where home crowds will witness this electrifying format on the biggest sporting stage.

Sunday's finals will determine which six teams qualify for the World Athletics Ultimate Championship in Budapest this September. Teams that miss the cut still have chances to qualify throughout the season based on their best times.

Jamaica's breakthrough proves we're just beginning to see what's possible when the world's fastest athletes collaborate across gender lines.
