Ai Campionati del Mondo di Pechino la Giamaica ha dominato entrambe le staffette 4x100m. In campo maschile il quartetto composto da Nesta Carter, Asafa Powell, Nickel Ashmeade e Usain Bolt ha demolito la concorrenza grazie ad un'ultima frazione fenomenale del dominatore di 100 e 200m, terminando con il tempo di 37"36. Al secondo posto la sorprendente Cina e al terzo il Canada, che hanno approfittato della squalifica degli americani (in precedenza secondi) a causa di un cambio scorretto.
Dominio giamaicano anche al femminile, con il tempo di 41"07 (nuovo record dei campionati). Il quartetto composto da Veronica Campbell-Brown, Natasha Morrison, Elaine Thompson e Shelly-Ann Fraser-Pryce ha staccato le avversarie sul rettilineo finale proprio con quest'ultima. Seconde le statunitensi e terze le atlete di Trinidad e Tobago.
L'americano Ashton Eaton ha realizzato il nuovo record del mondo nel decathlon, raggiungendo quota 9045 punti. Ha migliorato di 6 punti il suo precedente primato (9039), stabilito nel giugno del 2012. È il suo terzo titolo consecutivo dopo i Giochi di Londra nel 2012 e i Mondiali di Mosca nel 2013. L'argento è andato al canadese Damian Warner, mentre il bronzo è stato vinto dal tedesco Rico Freimuth.
