Philip Goodeve-Docker, 31, was trapped in a tent with winds blowing outside of 160mph and temperatures down to -20°C (-4°F) after a storm called a Piteraq hit his team just two days into their 30-day, 400-mile (644km) unsupported trek across the Greenland ice cap.
Before he set off, he wrote he had been inspired to embark on the "nutty" adventure by his late grandfather Patrick Pirie-Gordon, of Aberdeenshire, a treasurer and honorary vice-president for the Royal Geographical Society who had raised money for a number of polar expeditions.
An inquest into the death of Mr Goodeve-Docker heard he had fought to survive the storm along with team leader Roan Hackney, 31, and friend Andrew Norman, 33, when it hit the group on April 26, an inquest in Basingstoke, Hampshire, was told.
The events organiser, from Chilbolton, Hampshire, died hours before the group was finally rescued by helicopter at noon on April 28 in appalling weather conditions. The other men survived, but with frostbite, and Mr Norman has lost toes and fingers.
Mr Hackney told the hearing he knew the storm was coming and they set up camp and got ready and they were well prepared with all the right kit to deal with the conditions.
But he explained that very soon on April 26 the storm "rapidly escalated out of nowhere" and drifting snow and ice was soon crushing them inside the tent. Within hours, all three of the tents poles had snapped, forcing them to huddle in the outside porch of the tent and fight for their lives after the conditions started to take their toll.
Mr Hackney said he tried to go outside to move the snow but could not make it and visibility was 0.8in in front of his face.
All the time, the men were being squeezed in the porch of the tent and Mr Hackney said: "I was concerned there would be suffocation under a blanket of snow."
Mr Hackney called for help on a satellite phone and was told it was impossible to get a helicopter to them and so the men had to sit it out.
In Chilbolton, Mr Goodeve-Docker's family were trying to get the rescue brought forward after speaking to Mr Goodeve-Docker on the phone.
On his internet charity page, Mr Goodeve-Docker wrote of the dangers he would face travelling across one of the most "deadly landscapes in the world" on the world's second largest ice cap from east to west. "Part of my reasons for this frankly nutty adventure is my grandfather, Patrick Pirie-Gordon, who passed away two years ago," he wrote.
"Among his achievements were his key roles as treasurer and honorary vice-president for the Royal Geographical Society, helping fund polar exploration, and treasurer for the QNI (Queen's Nursing Institute). He was intensely passionate about both these institutions.
"It gave me added incentive to say yes to the expedition and, because of their fantastic work in nursing & helping those in need at home, to do my part for QNI. They really do fantastic work."
Mr Hackney told the inquest the men turned numb with frostbite.
"It was then the very real thought we might not make it formed in our minds - we were just trying to stay alive," he said.
By the morning of April 28, Mr Hackney told the hearing he was unconscious with hypothermia and said Mr Goodeve-Docker must had died a few hours before the rescue. "I heard the helicopter and the sound of people grabbing my hand and I was pulled out of the snow. I was carried to the helicopter. It was only later in hospital that I heard Andy had survived and Phil had died. For the last four hours I was unconscious."
Recording a verdict of misadventure, North Hampshire coroner Andrew Bradley said: "It's almost perverse that a fundraising drive taking place in a sense of adventure became the most appalling misadventure."
