Ultimate Championship, Day One: Jamaica Takes Relay Silver as Budapest Opens, and the Caribbean's Big Races Lie Ahead

The inaugural best-versus-best championship opened with a Jamaican silver in the mixed relay and a night that belonged to the favorites. The races that carry the Caribbean, Julien Alfred's 100 and Marileidy Paulino's 400, come on days two and three.

The first World Athletics Ultimate Championship opened in Budapest on September 11, 2026, and day one's headline Caribbean result came in the mixed 4x100 meters relay, where Jamaica ran 39.72 to take silver. The United States won it in a personal-best 39.64, and Great Britain took third in 40.26.

The Dominican Republic's Marileidy Paulino, the Olympic 400 meters champion, served notice for the days ahead. She topped her semi-final in 49.58, the fastest of the round, ahead of Bahrain's Salwa Eid Naser at 49.67. The 400 final, one of the region's best medal chances, is still to come.

Elsewhere the form book held on a night built for favorites. Masai Russell of the United States won the women's 100 meters hurdles in 12.22, holding off Nigeria's Tobi Amusan, who took silver in 12.34 and banked 75,000 dollars for second under the meet's rich prize scale. Mondo Duplantis was faultless to win the pole vault. Jakob Ingebrigtsen pulled away from Cole Hocker to take the 5000 meters. Ja'Kobe Tharp of the United States won the men's 110 meters hurdles by a single hundredth of a second.

The races that matter most to this region are still on the track. Julien Alfred of St. Lucia runs the women's 100. Jamaica's Oblique Seville, the reigning world champion, headlines the men's 100, with the open question of whether Kishane Thompson is fit to join him. And Paulino goes in the 400. Days two and three are where the Caribbean's medals will be won or lost. The Ledger files each day, with the full championship wrap on the final night.
