Kenton Cool: nine ascents of the world's highest mountain

British mountaineer Kenton Cool today broke two records, with his ninth ascent of Everest – and the first Tweet sent from the summit of the world’s highest peak.

Gloucestershire-based alpinist Cool’s nine ascents mark a new British record and his 135-character Tweet brought the previously remote 8,848m (29,029ft) peak into the Twittersphere.

His message was sent earlier today from the 37-year-old mountaineer, who describes himself as: ‘climber, Mountain Guide, conference keynote speaker, fish and chip connoisseur’.

In it, he said: “Everest summit no 9! 1st tweet from the top of the world thanks to a weak 3G signal & the awesome Samsung Galaxy S2 handset! @samsunguk.”

In 2009, Cool guided Sir Ranulph Fiennes to the summit of Everest on his second attempt.

He has also summited the mountain twice in one week, in 2007.

Mr Cool is married with one daughter, and is a director of Dream Guides.
