The incredible video shows huge chunks of ice racing straight towards Harry before he’s engulfed by the avalanche as he shelters behind a rock. He said: “We’d just reached the highest point in the trek and I separated from the group to take pictures on top of a hill/cliff edge. “While I was taking pictures I heard the sound of deep ice cracking behind me.” Read more world news SLAUGHTERED I was having beer after work when gunmen opened fire - people died screaming GUNBELIEVABLE Boy held by airport security after TOY GUNS spotted in Mario Bros backpack Harry admitted it would have been sensible to scramble for shelter straight away – but he said he initially felt “in control”. Yet as the avalanche grew closer he said it became harder to breathe. “When the snow started coming over and it got dark and harder to breath, I was bricking it and thought I might die,” he said. “Behind the rock it was like being inside a blizzard.

Harry, who holds the Guinness World Record for the most backflips in a sky dive, told news.com.au: “When it was coming towards me, I was thinking about a few things. “Initially, I was focusing on trying to get a good video. “I wasn’t really expecting it to get as close as it did, but when it came over the first hill I knew that there was nowhere to run because I was on the edge of a cliff, and that moving from where I was would be more dangerous. “When it came over the second hill was when I knew I’d need to use the cover right next to me. “Embarrassingly one of the main thoughts in my head was something like, ‘I hate when people can’t film avalanches properly, I’m going to show them how it’s done,’ which is when I decided to take the big risk of moving so late.” Read More on The Sun FAN-TASTIC How much does it cost to leave a fan on overnight?
