Britain's Anna Morris completed a hat-trick of gold medals at the Track Cycling World Championships in Shanghai as she won the women's madison on Saturday with Erin Boothman.

Wales' Morris, 31, and 19-year-old Boothman, from Scotland, took gold with 40 points - finishing ahead of France in second and Japan in third.

"I am quite speechless. It is going to take a while to sink in and reflect on it," Morris, a seven-time world champion, said.

"It has been a busy few days so now I have got time to let that soak in and enjoy it."

Morris is the first woman to win all three events - team pursuit, omnium and madison - in a single championships since the introduction of women's madison in 2017.

She won the women's omnium on Friday and team pursuit, along with Boothman, Josie Knight and Millie Couzens on Thursday.

England's Couzens, 22, claimed Britain's other gold medal on Saturday, coming out on top in the all-British women's individual pursuit final - beating 29-year-old Josie Knight to the gold by half a second.

Couzens led from the first lap to clock in a time of four minutes 21.505 seconds for her second gold at the championships.

"It is amazing, I am still a bit in shock to be honest. I had zero expectations going in," Couzens said.

Britain lead the medals table with a total of six golds.
