Fernanda Maciel achieved her goal – to run up and down Aconcagua in under 24 hours.

An impressive feat, the mountain stands at 6,691m high and a peak that had already seen a failed attempt for her, and many others.

Feeling stronger than ever, this time she became a legend of mountain running. The Brazilian ran 45km from the entrance of Aconcagua Provincial Park and to the peak of the mountain and back in 22h 52mins.

See what she has to say about her incredible achievement in the inspiring video clip above.

During the climb she battled snow, ice and steep gradients as well as dealing with running above the ‘death-zone’ – above 6,000m there is not enough oxygen for a human to breathe.

She had spent time training on and around the mountain before the attempt and was feeling strong in mind and body. That helped in her effort, but the climb took it’s toll, especially running at night in high altitude.

"It felt like I was drunk," Maciel said. "I lost a lot of energy from the cold in the dawn and spent a few hours running in a zigzag, very slowly. Only when the sun came out did I get better, I returned to my pace and the bad feeling wasn't there any more."
