Hiking from Lukla to Phakding in Nepal is just a small 7.8km trail, but it is the altitude that will bring you fatigue, I flew in from Kathmandu to Lukla and the body experienced a change of close to double from 1,400m to 2,860m and for someone from Singapore where the highest hill in Singapore is Bukit Timah Hill which stands at 164m in altitude, that change can kill anyone who isn't able to adapt to it.
