Elevation stephen King has done it.

The Australian Olympic champion is the first athlete to achieve a 10 metre (32 ft) altitude milestone in a single-day competition, after he became the first man to climb Mount Kilimanjaro, the highest mountain in Africa.

The 19-year-old, from Sydney, has climbed Kilimanara for the first time on Tuesday and will now set off for the summit of Mount Kilima on Thursday.

The 20-year old, who has been training at a gym on the Kenyan side of the mountain, has set a world record in a team event for the third time.

“The challenge is just so much more daunting than it was yesterday,” King told Channel Nine.

“I’m just really excited and happy that I’m now a part of a great team with the likes of Andrew Voss, Matt Brown, Timmy Williams and many others.”

The team has trained at a base camp at the base camp of Kilimanaros peak in Nairobi.

“It’s a great feeling for me and I’m so happy to be part of it,” King said.

“To be able to reach this high has been an incredible achievement for me, especially as I’ve been a long-distance runner in the past.”

King is set to start on Thursday’s climb at 11:45am, which means he will be about 2.5 hours away from the summit.

It’s an altitude of about 2,600 metres (9,000ft) and he’s currently climbing at an altitude that’s almost twice as high as the highest point on Mount Everest.

King was initially scheduled to climb Kilimanacos peak on June 16, but due to the coronavirus outbreak the race has been postponed.

King is one of the best athletes in the world and has climbed Mt Kilimanazos three times before.

In February this year, he was named one of The Guardian’s top 10 climbers of the year.
