The 16-year-old demonstrated insane technical content at the event, throwing FOUR quadruple jumps in her free program, three of which were decently landed.
The European bronze medalist nailed a quad salchow and a quad lutz before falling on a quadruple toe loop.
The error didn’t affect Trusova’s performance much, as she effortlessly landed another quad toe loop in combination with an oiler and a triple salchow in the second part of her routine.
Despite two falls, Trusova posted a whopping 248,63 points which turned out to be out of reach for the rest of the competitors, including Kostornaia, who settled for silver.
The skater, who opened a new season in Kazan, was practically faultless on her jumps, which didn’t include her signature triple axel.
The absence of ultra-c elements didn’t allow the skater to leapfrog Trusova in the final standings. Kostornaia collected 226,31 points, finishing second, a full 20 points behind Trusova.
Both skaters left Eteri Tutberidze’s camp this year and joined Evgeni Plushenko’s figure skating academy.
Bronze went to Maya Khromykh, who attempted to land a quad in her program, scoring 212,72 points.
The fifth and final stage of the Cup of Russia will be held in Moscow in December.
