Germany's Emanuel Buchmann (Bora-Hansgrohe) set the fastest known time for the Everest Challenge by completing the 11.6 km ascent near Etztal, Austria, in just under eight attempts, climbing 8,848 meters in the same section.

Buchman completed the challenge in just over 7 hours and 28 minutes, 14 minutes faster than American mountain bike champion Keegan Swenson.

Buchmann, 27, who finished fourth overall in the 2019 Tour de France, aims to raise 10 euros for every vertical meter (opens in new tab) climbed for Deutsche Kinderhilfswerk, an organization that works for disadvantaged children, Everest, an informal competition initiated by the Hells 500 club in Australia.

According to Buchman's ride uploaded to Strava (opens in new tab), he ran 162.19 km, climbing at a VAM of over 1,500 mph and reaching a maximum speed of 75.3 km/h on the descent.

But it also shows that he technically violated the simple rule of the challenge: pick any climb you want, anywhere in the world, and ride or run until you record a veldt of 8,848 meters. Buchmann started his ascent from Otz and descended the other side toward Heimingerberg, repeating the steep slope eight times.

"It was one of the hardest things I've ever done," Buchmann said in a team press release. I didn't expect to be in so much pain at the end."

"I got into a good rhythm at first, then decided to push hard, and after 7,000m of climbing I started to feel my muscles," Buchman said. I'm not used to this much load, so it started to hurt a lot. The last 1000m was brutal. But there were some fans and their support pushed me towards the finish.

"It feels great now to have broken the record here in Ötztal. As a professional, you don't usually have time for crazy stuff like that. It doesn't compare to the race at all, but I still think it was a strong performance and we are definitely on track for the Tour."

"But it's also important for me to make sure that people remember why I did this - the charity. I now want to do my part and encourage further donations to the Deutsches Kinderhilfswerk (German Children's Fund). Therefore, the project will remain online."

Buchman is the latest in a series of riders to take on the Everest Challenge, with American Katie Hall setting the fastest known female time of just over 10 hours.

Prior to Swenson's effort, retired professional Phil Guymon at one point held the Everest record of 7 hours 52 minutes. Kevin Belmarke of Hagens Berman Axiom also completed the climb in 8 hours 19 minutes.

Mark Cavendish (Bahrain McLaren) completed Everest in 10:37 on Zwift with Luke Rowe last month, and Giulio Ciccone (Trek Segafredo) ran over 10,000m in April on the Zwift terrace.
