Danny Roberts had to call it quits after completing nine of his target 14 laps due to concerns for his wellbeing during the challenge, which was hit by Storm Jorge.
The 29-year-old had aimed to climb the equivalent height of Mount Everest (8,848m). Snaefell is 620m high.
It was in aid of Huntington’s Disease Isle of Man and mental health charity REACH IOM.
He has so far raised more than £7,000, £2,000 above his £5,000 target.
A recovering Danny said: ’I’m disappointed I didn’t make it to 14 laps.
’It was going brilliantly but the weather was horrendous. On Saturday there were hailstones coming through and it was like a wind tunnel coming down the valley and I had that all the way to Snaefell.
’Without the weather, I would have cracked on and got it done.’
Starting at 8am on Saturday, Danny carried on regardless of the difficult weather conditions with breaks until 5pm on Sunday.
However, his friends noticed he was showing no interest in eating or drinking and called Danny’s doctor.
’People were talking, but I was too delusional to process what they were saying and I wasn’t eating or drinking. I had only peed once all that day and I was really dehydrated,’ Danny said.
’My doctor said that I needed to reel it in. I was disappointed, but your health is more important.’
Not one to give up, he has already made plans for another endurance challenge.
Last summer, Danny raised £2,000 towards Huntington’s Disease Isle of Man in memory of his grandmother who sadly died from the disease by carrying out a 24-hour continuous circuit challenge. He said: ’Doing these challenges is not only about your mental health, but to show people that you can go out and do things. I hope that it’s inspired people to try.’
This year he wanted to help REACH IOM, which was founded by his best friend Adam Hudgeon, as Danny witnessed Adam’s own personal struggle and a ’remarkable’ turnaround.
He added that like last time he was overwhelmed by the support from loved ones and strangers.
’Our gazebo on Laxey promenade blew down in the wind and The Laxey Beach Cafe owner let people stay under shelter and would bring me soup for free.
’I cannot thank her and everyone else enough for their support,’ Danny said.
Andy Harding, a director at DQ Advocates, said: ’I think everyone who knows Danny is in awe of his achievement. To climb in the region of 6,300 metres and complete the circuit nine times continuously, around 100 miles in total, is special in itself.
’To undertake such a challenge in what were largely horrendous weather conditions, including severe gales, snow and hail, was magnificent and all of us were pleased to support him along the way.’
