The epic expedition took place over four days at the end of February, raising vital funds for research into paediatric brain tumours
The expedition saw teams including Smith & Williamson, Barclays, JP Morgan, Goldman Sachs, global insurance broker BMS and Toby's Team, made up of seven mums including Toby's mum, Tanya.
With donations still coming in, the expedition is expected to exceed the £1million mark.
Along with 30 other intrepid challengers, Phil Spencer, the Channel 4 presenter of Location, Location, Location and Love it or List It joined Team Smith & Williamson on the charity's epic ski tour in Verbier, Switzerland.
Phil said: “ It was a personal Everest for everyone. It was simply incredible and something I would never have thought I would have been able to achieve. It was the epic challenge of my life!
Everest in the Alps: The Second Ascent, was inspired by Rob and is a demanding challenge that reflects the mountain his son, 10-year-old Toby, still has to climb in his fight against the disease.
“Everyone has their own Everest," said Rob
“It appeals on many levels. A lot of good people came together from all different walks of life and ultimately we've raised a lot of money for research that's been so underfunded."
Phil said: “Something that really resonates with me is talking about Toby's Everest and the challenges he faces. For us, this is our big challenge. I know I will never take part in such a physical challenge as big as this, so it's my personal Everest.
“It was unique. When you tell people they're immediately curious, not that they can really picture what 5.5 miles vertical actually looks like, or indeed might feel like, to try and climb."
Training was tough in itself. The vertical nature of the challenge presented everyone with their biggest problem. It's just not something most people were even remotely used to, explained Rob.
Rob said: “When we had low moments, we talked about Toby, and reminded ourselves why we're here."
Phil said: “The changing weather patterns made the expedition incredibly hard. The legs and body worked well but it was the relentlessness of the challenge that got to us.
“It was every single minute, from the moment you woke up until you went to sleep.
Along the route, the teams spent the nights in mountain huts, giving them a basic but well-earned rest and a chance to gather their strength and a short respite from temperatures as low as -30°C. Long days meant that they had to be back on the slopes as early as 5:30am each morning.
IFMGA Mountain Guide, Harry Taylor, was the lead guide for the challenge. He has climbed on Everest nine times, and is the second British man to have reached the summit without oxygen.
He explained the severity of the conditions the team's faced in Verbier: “ This was planned to be a physical event, and a great fundraising event, but the temperatures we are experiencing today are not a million miles from the -36°C temperatures I experienced on my summit day [on Everest].
“It's a very real test, and a very real experience for the teams that I'm sure they'll remember for a long time."
“Hitting the summit happened very quickly," said Phil.
“The last day was a really early start. I was tired and a few things went wrong in the first 20 mins of that day and I was out of sorts. It took me a while to find my rhythm, to get my positive head on.
“I felt like I was letting people down and realised I needed to stop panicking, that I needed to wake up and focus. Then we hit blizzard conditions for three hours with no communication and not really able to look around. It was a surreal 'heads down' kind of state.
“After a few hours, I had no idea we had climbed so far and then the call came down the line that we only had 250 metres to go. It was a shock to be honest. Then the smiles came out for everyone and the high spirits soared for the last hour.
“It was the ultimate elation; everyone was tired, happy, emotional – you name it. It was a wonderful feeling, finally finishing such a remarkable challenge."
Key to the challenge's success was Secret Compass, an expedition and adventure travel company at the forefront of project planning and risk management in remote and extreme environments.
Tom Bodkin, managing director of Secret Compass, said: “ It was a privilege to be able to support Rob and his family with Everest in the Alps, and take part in the challenge for the second time.
“The Second Ascent has not only proved the concept of the challenge, it has once again been a highly successful fundraiser for a cause in desperate need of more funding."
Funds raised by all the teams will go to The Everest Centre, financed by The Brain Tumour Charity with a global remit to research new treatments. The expedition is on course to raise £1million.
The centre will fund several vital research projects that will help us understand more about low grade paediatric brain tumours and trial new treatments.
Globally over 26,000 children have a low grade paediatric brain tumour and every year in the UK another 300 children are diagnosed. The location of low grade tumours in the brain often make them only partially operable. Consequently children often have to go through multiple rounds of invasive treatment like chemotherapy and radiotherapy, and relapse is a constant fear.
Phil said: “Everest in the Alps will make a difference for The Everest Centre and for vital research that just wasn't there before."
