In the 2019 Diamond League global series of meetings, American Noah Lyles won the men's final and Great Britain's Dina Asher-Smith won the women's final.[3] Regional 100 m titles decided that year included the Universiade, African Games, Pan American Games, European Games, Asian Championships, and South American Championships. The 2019 World Para Athletics Championships featured 100 m finals in 17 men's and 15 women's categories.[4][5]
Both World Championships winning times were the fastest recorded in the men's and women's divisions that year. No senior world or continental records in the 100 m were beaten in 2019.[6][7] Significant national records set that year included Abdul Hakim Sani Brown's run of 9.97 seconds for the men's Japanese record and Dina Asher-Smith's women's British record of 10.83.[8][9]
In the under-20 age category, Lalu Muhammad Zohri was the fastest man that year with 10.03 (a senior Indonesian record) and Sha'Carri Richardson of the United States was the fastest under-20 woman with 10.75 (a world under-20 record and third in the senior rankings).[10][11][12][13] In the under-18 category, Jamaicans Briana Williams (11.02) and Conroy Jones (10.32) were the fastest that year.[14][15]
Coleman's world title generated some controversy as he had successfully appealed a doping ban by the United States Anti-Doping Agency that season due to his missing three tests within a twelve-month period.[16]
