Tungesvik won the men's race in a time of 1 hour 16min and 47sec, nearly a minute ahead of the Russian Triathlon Federation's (RTF) Pavel Andreev, who failed with his bid for a ninth straight world title.

Medvedeva finished third ahead of her compatriot and reigning world champion Daria Rogozina, while Czech triathlete Aneta Grabmullerova finished fifth.

Nadezhda Belkina led an all-RTF podium in the women's under-23 category, finishing in a time of 1:39:30.

Olga Cheremisinova claimed silver, 45 seconds down from her compatriot, while Valeria Kuznetsova won the bronze medal.

Italy's Mattia Tanara earned the under-23 men's title in a time of 1:21:41, more than five minutes ahead of his closest challenger, RTF's Evgenii Evgrafov.
