"Knowing I've secured the globe is amazing," said Bankes.

Meanwhile 15-year-old Briton Mia Brookes won snowboard big air gold at the Junior World Championships.

She added gold to the silver she won earlier in the week in slopestyle in Leysin, Switzerland. The result guarantees her a place on the World Cup tour next season.

Bankes, who had a disappointing Olympics when she got knocked out in the quarter-finals, said: "The crystal globe has always been a dream for me, but I really didn't know if I'd ever manage to get the consistency to be able to fight for it."

She beat Italy's Michela Moioli, with Canada's Audrey McManiman third in Austria.

The eighth and final event of the 2021-22 season is held in Veysonnaz, Switzerland, on 20 March but neither Moioli nor Chloe Trespeuch of France can overhaul Bankes' 113-point lead.

Bankes followed up her World Cup victory in Montafon in December with back-to-back wins in Krasnoyarsk in January, before competing in the Beijing Olympics.

"With the start to the season I had, [winning the Crystal Globe] became a goal," she added.

"I'm just so happy and proud of what we've done as a team to achieve it, certainly after the disappointment of the Olympics."
