Ahead of his next seven summit attempt, Peter shares expert advice on how to train for mountaineering expeditions such as Denali and Everest
I climbed my first high-altitude mountain back in 2010. At 5,895m (19,340ft), Kilimanjaro is Africa’s highest peak and while I had some hillwalking behind me, I had no prior experience of trekking at altitude, wasn’t fit enough and didn’t have the right gear. In hindsight, I was fortunate to make the summit considering I was so underprepared.
