Australian’ 24-year-old Jacqui Bell is the youngest person lining up for the 323K Alps 2 Ocean Ultra in New Zealand

24-year-old Australian ultra-marathon runner Jacqui Bell is in New Zealand to tackle her longest ultra-marathon.

Bell is lining up in the Alps 2 Ocean Ultra on Sunday with 120 others from 14 countries to run 323 kilometers from Aoraki/Mt Cook to Oamaru in seven days mostly following the off road Alps 2 Ocean cycle trail.

Speaking from Christchurch New Zealand Airport on Wednesday, she told Stuff she expected the race to be "brutal". Completing it will bring her a step closer to being the youngest person in history to run an ultra-marathon on every continent in the world.

"I'm hoping the scenery makes up for the toughness of it. It's a lot of kms, and my body hasn't done any more than 250kms every.

"It's kind of like going into the unknown in that next 73km ... but I'll just try and enjoy it."

Bell said she was looking forward to the "beautiful landscape" in New Zealand.

"I can't wait to clock off from the everyday stresses of life and get to run every day in the mountains.

"I've never been to New Zealand ... I'm not sure what I'm in for."

Bell said she couldn't resist the idea of running 323km.

"It's going to be amazing," she said.
