GS courses, by contrast, are typically about the same pitch as a black run; gates will approximate the same 25-35 m turns that a good skier will carve on a firm 30 degree slope. Again, though, the real issue is speed control. If a GS course is too steep, the skis will accelerate too much between gates, creating unreasonably high G-forces in the turn. So as with a downhill or SG, you want a hill that's as steep as possible that will allow a strong skier to hold a line. And again, transitions help. First conclusion: The speeds I quoted for WC racers will be faster than almost any recreational skier can achieve on the same slope without losing control of his/her line.
Now obviously, you can straightline anything; I see intermediates doing it all the time. But on firm snow at the pitch of a GS course, straightlining after a few seconds will produce significant periods when the ski is no longer in contact with the snow. Any idea that anyone on Epic would be "in control" at that point is illusionary physics. It's just about luck and balance. IMO, whatever you want to call that, it's not skiing, anymore than twisting the throttle of a liter class bike and managing not to get ripped off the seat is riding a motorcycle.
2) The speeds I quoted are averages, determined by distance and time, not by a speed trap.
3) If you're using GPS to calculate your speed, suggest you consult the other thread, some good info on the problems of assuming accuracy. If you're using a radar gun, suggest you Google the various problems they have which tend to produce lot of variance. If you're using a laser, it's pretty accurate and you're pretty rich.
Conclusion: I do not believe most of the speeds I read about on these threads. Sorry.
Nice , It's OK though, the OP has been answered on page 1.
Average speed from start to finish, not average speed in the middle of the course, or at the fastest portion of the course.
for comparison, the maximum speed on a DH is Johan Clarey's 100.6 mph at the Wengen downhill in Switzerland.
Skiing in control means being able to make turns that avoid the skiers and objects in front of you, not being able to make the turn set by an evil course setter to throw you off your game and seperate the best skiers from the good skiers. You can still ski in control faster without making the gate even if you are not the best skier.
If you're saying that anyone skiing faster than the average speed on a GS course set is skiing out of control or that the average speed on a gs course is the limit for skiers who are not WC athletes skiing in control, you have lost a lot of credibility.
To save time, here's a summary of those threads.
How fast do you ski?
a:I ski x miles per hour.
b:That's not possible, unless you are on a WC team, and wearing a speed suit. What makes you think you ski that fast?
a:I'm going by comparing it to speeds on my bicycle that has a speedometer, and how much eye protection I need to see, speeds on a motorcycle, etc..
b:That's not good enough, you need better measurements than that.
a:OK, I bought a $750 handheld GPS unit that records every second and has a rated accuracy of plus or minus y mph, and it says consistently that I ski x miles per hour.
b:GPS is highly inaccurate. Unless you had a radar gun showing your speed, you were not going that fast.
c:I went to the TGR speed day, we had a radar gun, I skied x miles an hour, another skier skied x miles an hour switch in baggy clothes.
b:That radar must have been faulty.
a:A couple of decades ago, I went to the Jay Peak Citizen's race as a last minute entry and they used a calibrated radar gun to show my speed was x miles an hour wearing a parka and jeans, even though I had to stand up out of my tuck for several seconds to kill speed until some clown standing in the middle of the course looking uphill to see if there was another skier coming down got out of the way, and I know the speed was much lower than what I usually ski when going for speed.
b:I don't believe it.
On the other hand, it is summer here and those threads are entertaining; go ahead and read 'em all.
