Roman Repilov sealed the men's sprint and singles double to complete a clean sweep of the individual titles for Russia at their home Luge World Championships in Sochi.
The 23-year-old clinched his maiden singles world title in a dramatic competition after Olympic champion David Gleirscher of Austria crashed on the final run at Sanki Sliding Center.
Gleirscher was the last athlete to take to the course after producing the fastest first run of 51.466sec but the crash ended his chances of leapfrogging Repinov into top spot.
The Russian, second after the opening run, earned gold in a combined time of 1min 43.099sec.
Austrian Jonas Müller, the 2019 world sprint champion, was 0.032 adrift in silver medal position.
Müller's compatriot Wolfgang Kindl did enough for bronze after clocking 1:43.301, although the Austrian team's results were overshadowed by Gleirscher failing to secure gold.
"After winning the world title in the sprint I was the favourite on my home track in front of a home crowd," said Repilov.
"David Gleirscher’s track record inspired me for the second run.
"I’m really sorry he crashed, but that’s luge for you."
Victory for Repilov ensured Russia won all four individual titles on home ice after Ekaterina Katnikova triumphed in the women's sprint and singles competitions.
Russia also topped the podium in the men's doubles sprint event thanks to Alexander Denisyev and Vladislav Antonov.
Germany won the mixed relay as Julia Taubitz, Johannes Ludwig, Toni Eggert and Sascha Benecken clocked 2:44.213 to claim gold.
Kendija Aparjode, Kristers Aparjods, Andris Šics and Juris Šics of Latvia finished in 2:44.534 to earn silver, while bronze went to the American team of Summer Britcher, Tucker West, Chris Mazdzer and Jayson Terdiman.
