Vladislav Dikidzhi was the first Russian skater to perform a quad Axel cleanly. The Axel is considered the most difficult jump among the existing ones.
Only one skater in the world has mastered this element - an American with Russian roots, Ilya Malinin. Yuzuru Hanyu most persistently sought to take this height, but he never achieved it in official tournaments. The race for this most difficult element began back in 2018, and Russian Arthur Dmitriev Jr. was first to try to perform it at competitions.
