PowderGuide: Hi Basti, it's great that you're here and have time for us. How did you actually get into ski mountaineering?
Basti Haag: I was practically born with skis. My parents are both state-certified ski instructors and put me on skis when I could barely walk. I "only" skied downhill at first. The big change came during my studies. On the one hand, I no longer had the money for the lift pass, and on the other, I only had proper touring equipment then.
PG: Why ski mountaineering on such big mountains and why always at speed?
Basti: The high mountains were simply the logical consequence of what we had done before. I spent many years with my buddy Beni Böhm in the Bavarian and Tyrolean Alps, then in the Western Alps, then in South America and later in the Himalayas. In the end, we wanted to test ourselves, we wanted to know whether we could make it up the 8000 meter peaks. Well, and the whole thing at speed. Speed is definitely more Beni's discipline. I was always looking for lines on how to ski down an 8000 meter peak. If I can combine that with a speed ascent, it's perfect. So a speed ascent means going up from the base camp and back down again in one go, without camp chains, without overnight stays.
PG: How much do you train for it?
Basti: Training is a passion for us; I'm happy when I can train. If I can, I train every day. I don't really have a plan. In winter, I just try to get on my skis every day and then I prefer to run 3000 meters in altitude. But 2000 is also okay, but I'm a bit dissatisfied at 1000.
PG: What was your greatest success?
Basti: The ski ascent on Gasherbrum II and of course the speed ascent, but even more so the ski ascent from the summit to base camp and the whole thing without touching a rope!
