evidence: Training to Climb Mount Everest [...] I could complete long hard treks as well as practice my technical winter climbing skills, all in difficult conditions. Climbing Everest is 80% mental. Having experience and lots of it would be really important. Irish and Scottish winters would help me test out my clothing and test every piece of kit. Mount Everest is also a physical challenge so being as prepared on all fronts was my goal. [...] After 6 weeks at Everest Base Camp and adjusting well to the low levels of oxygen, then it was time to go for it. We would take seven days to push all the way to the summit of Mount Everest and back down again.
