Snowboarding: Kiwi Zoi Sadowski-Synnott celebrates birthday with win at Natural Selection Revelstoke

Kiwi Zoi Sadowski-Synnott has celebrated her 22nd birthday with victory at the Natural Selection Revelstoke.

Sadowski-Synnott battled through the competition's most challenging conditions in history at the Selkirk Mountains to claim her 24th consecutive podium finish in the last three years.

After besting American opponent Hailey Langland in the semi-finals, she advanced to the finals against Big Mountain shredder Elewna Hight.

Sadowski-Synnott showed out on the big stage to earn her second-highest score of the day of 79.2, which was also named Run of the Day, to claim first place.

"I feel super honoured and privileged to be able to compete in this competition because it's the best backcountry riders in the world, riding the best snow in the most psycho terrain," she said after her victory.

"To be part of it is pretty insane. Coming from a slopestyle and big air background, it's so different but kind of the same in the sense that you're just trying to ride your best and perform on the day.

 "I haven't ridden a lot of pillows in my life, so to come here and ride this definitely was a learning curve and I'm super stoked--I feel like I pushed myself and everyone rode some insanely sick lines."
