But Kenton Cool, the Briton with the most ascents of Mount Everest to his name, has now broken another record – by becoming the first person to send a tweet from the summit.
The feat became possible after the Nepalese mobile network operator Ncell installed a 3G station at the mountain’s base camp last October.
Cool wrote: ‘Everest summit no 9! 1st tweet from the top of the world!’
He also told technology website mashable.com: ‘I’ve climbed Everest before but have never been able to share the exhilaration I experience when I reach the top with those back home.’
