The 22-year-old Slovenian achieved five tops and five zones in Group A, and Brooke Raboutou of the United States made four tops and five zones in Group B.

Raboutou’s compatriot Natalia Grossman, winner of two consecutive gold medals in last month’s Boulder World Cups in Salt Lake City, beating Garnbret into silver-medal position in the second, also qualified for the women’s semi-final.

The action took place under searing Alpine sunshine, although no spectators were allowed at the Kletterzentrum venue because of COVID-19 restrictions.

Three home climbers also joined the top 20 competitors who went through to the semi-finals - Sandra Lettner, silver medallist at the 2018 Summer Youth Olympic Games in Buenos Aires, and her Austrian team-mates Johanna Färber and Franziska Sterrer.

Meanwhile, home favourite Jakob Schubert, Tokyo 2020-bound, headed the men’s Group B qualifying with three tops and five zones and will be joined in the semi-finals by compatriot Nicolai Uznik.

Yoshiyuki Ogata of Japan achieved five tops and five zones to place first in group A.

Earlier, the 22-year-old Garnbret, whose six world titles include two in bouldering and two in lead climbing as well as two in combined, had qualified for the semi-finals in this season’s first World Cup lead competition, finishing top after being the only athlete to top both routes.

She was followed by Italian Laura Rogora, winner of the gold medal in the sole lead World Cup of the 2020 season, and Raboutou, with the pair being the only two athletes aside from Garnbret to secure a top in the women’s event.

In the men’s lead qualifying Adam Ondra of the Czech Republic, who has already won bouldering at two of the three World Cups held so far this season, was the outstanding climber, with Schubert taking second place followed by Alexander Megos of Germany.
