Tsang Yin-hung, who hosted the event on the 2017 tour, reached the top in 25 hours and 50 minutes.
Hong Kong mountaineer Tsang Yin-hung, a former teacher, has recorded a speed bump for Everest with a woman with less than 26 hours, an official in Nepal said on Thursday.
Tsang, 44, climbed 8,848.86 meters (29,031 feet) during a 25-hour and 50-minute recording session on Sunday, Everest Gyanendra Shrestha said.
“He left the camp at 1:20 pm on Saturday and arrived (above) at 3:10 pm the next day,” Shrestha told AFP.
But Tsang still needs to present his case to Guinness World Record officials in order to get a license for his work, he added.
The government of Nepal acknowledges that mountaineers have arrived at the event but have not issued a written certificate.
Tsang, also known as Ada, the pilot is now on his way to Kathmandu and has not responded.
The fastest woman to conquer Everest was Nephun Phunjo Jhangmu Lama as she finished her climb in 39 hours 6 minutes.
In 2017, Tsang became the first woman in Hong Kong to reach the top. It was his third attempt to elevate the Himalayan peak.
Nepal has issued 408 Everest certificates for this summer’s season after the season was abolished due to the epidemic.
As many as 350 people have reached the top of the mountain this spring, the Department of Tourism says, although the country is battling coronavirus.
But two such teams lost their way of travel after some members of their team were tested.
