The world records set earlier this year by Bahamian hurdler Devynne Charlton and Kenyan long-distance runner Peres Jepchirchir have now been ratified by World Athletics.
Charlton lowered the 60m hurdles world record to 7.65 seconds on March 3 in Glasgow, Scotland.
She broke the world record and secured her first global title at the World Athletics Indoor Championships.
Kenya's Peres Jepchirchir rewrote the record book as she ran 2:16:16 to improve the women-only world marathon record by 45 seconds at the London Marathon.
The 28-year-old sprinter had previously shared the world record of 7.67 with Tia Jones of the United States.
“This means a whole lot because I have set myself goals,” Charlton said after improving the record by another 0.02 in Glasgow.
“I have not changed my technique much – just a few tweaks – but I have been working hard off the track, making sure my mental health is good and working with a sports psychologist.
“Just taking care of myself. Indoors really plays well to my skillset too.”

On April 21 this year, Kenya’s Jepchirchir also rewrote the record book as she ran 2:16:16 to improve the women-only world marathon record by 45 seconds at the London Marathon.
With a rich field of star marathoners, Mary Keitany’s women-only world record of 2:17:01 was the big target.
At the end of the gruelling race, Jepchirchir beat it, clocking 2:16:16.
She finished seven seconds ahead of Ethiopia's Tigist Assefa.
Kenya's Joyciline Jepkosgei (2:16:24) and Ethiopia's Megertu Alemu(2:16:34) ensured that it was the first marathon in which four women finished inside 2:17.
