The Tour de Ski prologue was as interesting as I hoped. In the women’s race, Petra used her sprint power to take a convincing victory by 2.1s over Korosteleva and three times that much over Kowalczyk. Miriam Goessner of Germany held the top spot for a long time and eventually wound up a surprising fifth, with Arianna Follis in between. Petra’s gonna be great in the classical pursuit tomorrow. In
