    I was just watching some old video of Hermann Maier and the commentator (Karen Lee Gartiner) mentioned that he had successfully improved his gliding skills between seasons. Beyond a slippery tuck and trying to keep your skis flat and swimming what elements make comprise good gliding skills. Equal weight distribution left and right? Neutral stance or weight back or forward? Wider than normal or usual stance? More suspension travel in the legs or a low tuck? What kind of things are useful to practice to improve gliding efficiency? I'm the just about the only one in my club interested in racing DH so I have to do it alone.

    @Doug Briggs will have some suggestions. You want stance width so skis are flat. Too wide and they're on edge. As for arms inside legs, in front, or outside, this may simply depend on body type.
    It seems like the good gliders remain supple over bumps while still maintaining tension/strength. This may be pyschological, experience, and body type related. Can you be soft and relaxed at speed?

    Check this out on tucking. Bully= bullet tuck.

    @Doug Briggs advice is likely better, but until he replies here my shot at it.

    To achieve maximum glide you want to achieve the least resistance on the snow possible and this is not a one solution answer.

    Consider as you gliding in any condition trying to achieve a lose ski condition (no edge engagement), floaty, rock back and forth, side to side and so on. When you feel that you don’t have control and the ski is getting ahead of you IMHO you likely have the start of a good glide.

    Now as to body position....help.... I’ll defer that to someone with a better answer.

    Run your base bevels about 1 cm into the Ptex so the steel edges are mostly off the snow when you are going straight.
    Snow is fast, metal is slow.
    Of course you have to be good enough to deal with really squirrely skis and delayed hookup but you want to go fast....

    I am interested in this as well. Wind tunnel training was mentioned. Anyone have contact details for where I can rent access in the Northeast? @James, I'll bet you know...

    Who are Team Sky and what do you mean by (+ asthma meds) beyond that obvious?

    My base bevel is set at 1 degree, if I were to take a couple of strokes with a 0.75 degree bevel tool it would fair my 1 degree bevel into the ptex do you suppose that would improve glide without changing the hook up?

    Going to 0.7 from 1 would probably get into the Ptex a couple of millimeters.
    The skis could be faster but I bet you would notice the difference.

    You could join TGR Forums, or try a different GPS based phone app. It makes most of the folks around here really fast.

    The bringing your base edge into the ptex seems dubious to me. Your making less surface area which could be faster given a perfect flat surface. You're also increasing the tendency of the ski to wobble. Introducing side to side instability could slow you more than the reduced surface friction. Don't know. I would bet this has been tested fairly extensively.

    Maybe @Primoz knows what they do for base tuning and whether they bring the base bevel into the ptex. If it was really faster, why not just design the ski base this way for speed skis? Landing jumps - not so good.

    Why don't you just increase the bevel of the metal? Downhill uses bevels well beyond 1 degree.

    HOW SCIENCE TURNED A STRUGGLING PRO SKIER INTO AN OLYMPIC MEDAL CONTENDER

    "He spends more time in the wind tunnels than anyone else. And he’s good at it. It turns out that standing still is a skill that is highly amenable to training. With enough strength, body control, and concentration you can learn how to be a statue in a hurricane. Then there are the subtler lessons. For example, the wind tunnel sessions helped Nyman discover that keeping his hands forward and his elbows together consistently reduces drag. In this position, wind slams into Nyman’s chest and funnels down between his legs; his arms and hands are essentially invisible, generating no additional resistance."
    https://www.wired.com/2014/02/ski-run-nyman-sochi-olympics/

    It's hard to interpret the above. The other style seems to be keeping elbows in front of knees or legs.

    The description doesn't match the photos.

    It's likely that less than five minutes talking with Daron or any of these guys would settle the issues.
    Doing it in a course is another matter, and the best tucker/glider isn't necessarily the fastest. That's also why Hermann Maier preferred super g. "No boring gliding sections" as he said.

    A study-
