KATHMANDU: Hong Kong mountaineer Tsang Yin-hung has recorded the world’s fastest ascent of Everest by a woman with a time of just under 26 hours, a Nepal official said Thursday.

Tsang, 44, scaled the 8,848.86-metre (29,031 feet) mountain in a record time of 25 hours and 50 minutes on Sunday, Everest base camp’s government liaison officer Gyanendra Shrestha said. “She left the base camp at 1:20 pm on Saturday and reached (the top at) 3:10 pm the next day,” Shrestha told AFP.

But Tsang still needs to present her claim to officials from Guinness World Records to receive certification of her feat, he added.
