TWO Americans, one Canadian and one Briton – alone on the biggest wall of the world’s highest mountain.

That is a story which will go before the audience at Lochgelly Centre on Saturday February 10.

No high altitude porters, no ladders, no oxygen, no satellite phone, no radios. And no hope of outside help if anything went wrong.

But they succeeded on a spectacularly difficult new route up the East Face, with Stephen Venables becoming the first Briton to reach the summit without supplementary oxygen.

He also, unintentionally, set a new record for surviving a night alone in the open at extreme altitude. In this spellbinding and beautifully illustrated 30th anniversary talk he recounts one of the most remarkable ascents of Everest.

As Reinhold Messner said: "Probably the most adventurous ascent in Everest’s history."
