Agreed. The guy surely achieves incredible values of VAM when running/skiing uphill. He's got a superb engine and low body mass and can be a great climber. Obviously his leg muscles need to switch to cycling effort, which is most crucial part. This is the guy to watch and I wouldn't be surprised if he becomes a top climber at some point.Ski Mountaineering also has the vertical race that is just a single climb with a mass start and the short sprint events (that stuff is horrible and even makes XC skiing sprints look great), not just the classic Marathon races with Multiple ascents and descents or the individual with 1 climb and 1 descent. Palzer has been 2nd at the WC in both the vertical race and the sprint, one would assume that athletes who compete in those have a high VO2max (and a great power to weight ration when it comes to the vertical).
