Day 1 of the 2026 World Athletics U20 Championships on Wednesday in Eugene, Ore., delivered PBs, national records, and dramatic finishes, but also its share of heartbreak. He took the world U20 cross-country title in January, making this his second straight world championship win, while his teammate Nehemiah Kipngeno finished second in 13:30.09. She was a silver medallist at her last U20 Championship in Lima, Peru and claimed bronze in January’s World U20 Cross-Country Championships. The final event of the night, the mixed 4x400m relay, produced one of the meet’s most memorable races, with five national U20 records and a world U20 record. Czechia edged the Australians for silver with a NU20R of 3:18.16, while the U.S. quartet of Joshua Shelton, Taylor-Nicole Overton, Jaelen Hunter and Olivia Harris stormed to gold in a world U20 record of 3:15.31.
