The third day of the World Para Swimming World Series in Glasgow produced six world records in a programme of multi-classification finals - and three of them came in the women’s 100 metres backstroke, where Italy's Carlotta Gilli, Britain’s Alice Tai and Xinyi Wang of China all set new marks to take gold, silver and bronze medals respectively.

Tai, an S8 classification swimmer who had earned the gold medal in the 100 metres freestyle on the opening day at the Tollcross International Swimming Centre, clocked 1min 08.09sec, worth 1007 points, with Xinyi, an S11 swimmer, taking bronze in 1:17.81, earning 1005 points.

The gold went to Gilli, who clocked 1:06.03 to gain a winning total of 1037 points.

"I’m really pleased with the swim," said Tai.

"It’s the fastest I’ve gone since 2017 [when an S10] so it’s showing that I’m going in the right direction. 

"Going into the race I thought it would take a world record to win but the top three all got them so it was a great final."

All athletes' results at each World Series edition are calculated using a standardised World Para Swimming points system via an online virtual competition platform.

This ensures that the overall World Series winner will be the best performing athlete over the duration of the series, meaning every performance counts.

A world record of 1:05.42 in the women’s 50m breaststroke earned gold for 15-year-old home S2 swimmer Ellie Challis.

Her rival Leanne Smith of the United States touched first in 1:02.89, but swimming in a lower class Challis’ world record time secured her 1047 points and World Series gold.

Smith took the silver medal with  a points total of 586.

The bronze was claimed by another S3 swimmer, I Rodriguez Martinez of Spain, who clocked 1:30.22 for 198 points. 

Britain’s Scott Quin, an S14 swimmer, had an outstanding day as he broke the  men’s 100m breaststroke world record in the morning's heat with 1:05.28 and then secured gold as his time of 1:05.53 earned 1032 points.

Spain’s Antoni Bertran took the silver, in the S5 category, clocked 1:30.28 for 944 points, while Colombia’s S7 swimmer Carlos Zarate clocked 1:14.20 for 932.

"I’m happy with the way I swam tonight," said Quin.

"It’s very hard to go 65.2 and then 65.5, so that’s the first time I’ve ever gone 65 twice in one day, so I couldn’t really expect to go even quicker."

Germany’s Elena Krawzow also produced a world record on the night.

The S12 category swimmer clocked  1:14.02 in the women’s 100m breaststroke to earn the gold medal with 1086 points.

Britons filled the two other podium places as Maisie Summers-Newton, in the S6 category, clocked 1:34.31 to earn 978 points and silver, and Brock Whiston, in the S8 class, clocked 1:18.50 for 950 and bronze.

Azerbaijan’s Raman Salei took the gold medal in the men’s 100m backstroke - the S12 swimmer earned 938 points for a time of 1:00.61.

The silver medal went to Britain’s Jordan Catchpole, from the S14 class, who clocked 1:00.70 to total 930 points, with compatriot Stephen Clegg taking bronze as his 1:01.30 earned 907.

Both the British times were national records.

The men’s 50m breaststroke was won by Japan’s Takayuki Suzuki, an S3 swimmer, who clocked 50.14sec for 852 points, with the silver medal being earned by Spain’s Ivan Fernandez, also in the S3 class, whose 1:03.51 timing earned 419.
