Physical Preparation: Six Months Is the Minimum

Island Peak demands serious aerobic capacity . The summit day alone covers roughly 1,100 metres of vertical gain at altitude, carrying a pack with crampons, ice axe, harness, and layers. You will do this starting from 5,100m after two weeks of cumulative…
