Kulizhnikov on fire at World Cup in Poland
Russia's Pavel Kulizhnikov enjoyed a dominant day in Poland as he claimed 500m and 1000m ISU Speed Skating World Cup golds.
The 24-year-old broke track records on his way to wins in both events in Tomaszow Mazowiecki, first claiming the shorter title in a time of 34.834 ahead of Ryohei Haga of Japan and Havard Holmefjord Lorentzen from Norway.
He then doubled up in the 1000m in a time of 1:09.238, beating Netherlands' Kai Verbij and Lorentzen once more.
In the ladies 500m, Austria's Vanessa Herzog took gold, seeing off Russian duo Olga Fatkulina and Daria Kachanova, who also took third in the 1000m behind champion Brittany Bowe of the USA and Japan's Miho Takagi.
Takagi was part of the Japanese women's team that clinched victory in the women's team pursuit, with their male counterparts matching them by taking the equivalent men's event.
