Nepal, Oct. 15 -- Nepali Times: You just climbed Mt Everest without oxygen and then skied down the mountain. How does one even train for something like that?

Andrzej Bargiel: What made skiing down Everest possible was all the years of experience I've gained in high-altitude mountains. Spending a lot of time in the high mountains helps me read the snow, the conditions, and potential hazards. I need to ski often, especially in steep and exposed terrain, so that it becomes a place where I feel completely at home.

I also climb regularly, I am an IFMGA mountain guide. I also run, ride a bike, and work out in the gym. Like in any endurance sport, I have to prepare my body for the demands of an expedition.

What motivated you to do Everest?...
