Kamila Valieva took a commanding lead on the first day of the Rostelecom Cup leg of the International Skating Union (ISU) Grand Prix of Figure Skating, by breaking the world record in the women's short programme in Sochi.

She expectedly topped the standings in front of her compatriot Elizaveta Tuktamysheva at the Iceberg Skating Palace with a score of 87.42 to her opponent's 80.10 - in doing so, she broke the world record.

Fellow Russian Alena Kostornaia set the previous best in 2019 with a score of 85.45.

"Today I am satisfied with my skate, happy that the coaches said good words to me," said the 15-year-old, according to Reuters.

"Today I did my absolute maximum [but] there is always room to grow."

A long way back is the United States' Mariah Bell in third on 69.37, with a decent gap back to Madeline Schizas of Canada.

Russians Victoria Sinitsina and Nikita Katsalapov are top of the ice dance rankings on home soil after the rhythm dance section.

They are far in front of the rest of the field with a total of 86.81, with Charlene Guignard and Marci Fabbri of Italy in second on 79.56.

Laurence Fournier Beaudry and Nikolaj Sorensen of Canada are in third on 76.39, marginally in front of the Spanish duo Sara Hurtado and Kirill Khaliavin.

More Russian success came in the pairs short programme, with all three of the top spots filled by home skaters.

Leading by a thin margin are Daria Pavliuchenko and Denis Khodykin on 73.91, less than half a point up on Anastasia Mishina and Aleksandr Galliamov who hold a score of 73.64.

Iasmina Kadyrova and Ivan Balchenko are comfortably in third on 69.39, with Americans Audrey Lu and Misha Mitrofanov the first non-Russians, in fourth place with a score of 64.97.

Kazuki Tomono of Japan leads the men's standings after the short programme, holding a narrow lead with a points total of 95.81.

His high score on his elements put him just in front of Georgia's Morisi Kviteashvili, who was marginally ahead on component score, but had a slightly lower element total, adding up to 95.37.

A chasm exists between the two and the rest of the field, with Canadian Roman Sadovsky currently sitting third on 84.59, losing some opening element points.

He is just 0.11 points in front of the top Russian, Mikhail Kolyada who is on 84.48, followed by American Camden Pulkinen and Michal Brezina of Czech Republic close behind in fifth and sixth.

Action continues tomorrow with the free skate and free dancing.

This is the last qualifier for the ISU Grand Prix of Figure Skating Final in Osaka next month.
