An elite adventurer is heading in the right direction to make historical past on Tuesday by changing into the primary Irish nationwide ever to climb Mount Everest with out oxygen.
But his gruelling preparations – which embody climbing two separate 6,000m Himalayan mountains with out oxygen in latest weeks – seem to have paid off, as he ready himself for the ultimate push to the highest of Everest.
However, the 39-year-old, who has spent greater than 50 days in Nepal acclimatising to the situations, insisted he’s taking nothing as a right forward of “summit day”.
He mentioned: “This expedition has been quite a bit more durable than I assumed. I’ve discovered that climbing with out oxygen is much more difficult than something I’ve executed earlier than.
“Without oxygen, you move twice as slowly as you would, and the lack of oxygen can affect your decision-making. You are also far colder on the mountain without oxygen than you would be, so there’s a lot of different complications happening at the same time.”
However, McManus – who runs Dublin-based journey journey firm Earth’s Edge – mentioned he feels assured he’ll achieve his history-making mission to the summit of the 8,850m peak by Tuesday.
He continued: “I’ve executed all the pieces I presumably can to get thus far, together with three rotations of Everest, whereby I’ve been steadily edging nearer to the summit – the final climb being as much as 7,850m. I’ve additionally just lately climbed two separate 6,000m mountains with out oxygen in preparation for this.
“So I feel well prepared, and am determined to make that final ascent and become the first person from Ireland to make it to the top of Everest without oxygen.”
To date simply 216 climbers have reached the highest of Everest with out using supplementary oxygen.
Before the feat was first achieved in May 1978 by main mountaineers Reinhold Messner and Peter Habeler, most consultants believed the human physique wouldn’t have the ability to deal with the low oxygen ranges [about 30 per cent of what they are at sea level] close to to the highest of the towering peak.
During the expedition, McManus has additionally been aiming to lift publicity for the Sherpa mountain guides and different low-paid employees within the area who he feels are exploited.
He added: “Over one million folks work in tourism in Nepal and round 54,000 of them are employed as guides, porters and cooks throughout the three-month climbing season every spring.
“Many of them are not being treated fairly, as there’s no employment law or minimum pay. The industry needs to be regulated, so these people are treated and paid properly.”
