Three local teenagers have helped New Zealand to its most successful ever day at the Winter Youth Olympic Games.

Luke Harrold (freeski), Lucia Georgalli (snowboard) and Campbell Melville Ives (snowboard) each won a bronze medal on Big Air finals day at Welli Helli Ski Resort in South Korea.

Luke opened the account for the Kiwis, stomping a right double cork 1440 with a safety grab in his first run. The 15-year-old backed that up with a left double cork 1440 with a stale grab in his second run for a solid score of 172.25.

“It’s a pretty amazing feeling, I’ve been working towards this competition for a while and to come out with third place is a dream,” Luke said.

Lucia was up next in the women’s snowboard, looking to add to the silver medal she won earlier in the week in slopestyle.

The 17-year-old landed a backside 900, followed by a frontside 720 in her third run to secure the podium spot.

“I didn’t really expect to medal,” Lucia said.

“I’m kind of in disbelief but it’s awesome and I’m really stoked.”

Campbell Melville Ives (17) rounded out the day for New Zealand landing a cab 1440 with an indy grab in his first run, backing it up with a switch back 1260 in his second.

“I’m pretty happy, it was a great competition,” Campbell said.

Campbell and Luke will compete in the men’s halfpipe on January 31, while Lucia now travels back to Wānaka before heading to the Northern Hemisphere World Cup circuit.
