Denali has a summit elevation of 6,194 m above sea level.

It is also known as Mount McKinley and is located in Alaksa.

Jane said Denali was her most challenging climb. She had to carry a pack that weighed 45kg and the descent took 24 hours without a break.

The weather was bad with high winds and a lot of snow.

"There was no place to stop and hide from the weather so you just have to keep on moving."
