and just to confirm, I went back into history to get the speed track.....:)   As you can see as this was my first time on a DH ski for a couple of years (and the first time on this particular ski) it shows a build up over 4 runs from the low 60s .....and then you can see where I switched back to a GS ski...

I don't ski as fast as I used to but on our Midwest slopes I'm between 18 & 33 according to a couple of ski tracking apps I've tried this year. When in the Rockies I can let them run a bit more but I didn't have the tracking apps then. I'm eager to see next year.
Anyone know how accurate these apps are?

I'm pretty sure everyone in Ontario skis faster than me.smile.gif

I am going to troll a little:

https://en.wikipedia.org/wiki/Downhill

Average speed of downhill skier is about 80 mph (assuming really good slope, no other skiers, special equipment and ski suite). You are doing pretty well, considering that you don't have anything above and skiing on the public, not race course. Have you though about applying to US or Canada Olympic ski team?

It's a lot easier when you don't have to make the gates.  However, if you crash, well, good luck with that.

Fairly? With a good signal from multiple GPS satellites, and on a straight line, they can be very accurate. I've run mine in my car several times and it very much matches the speedometer (I might have reported on that earlier in this thread).

 

So it should be fairly accurate as long as it's got a good signal... though it's probably somewhat still prone to glitches, particularly in factoring in drops and tight turns on a mountain. I know at least one time when SkiTracks clocked me at over 30 MPH as I got off the lift at the top. And I'm pretty sure the lift doesn't eject you that fast.

I'll add to this a little.... a bit earlier in the thread were some links to TGR threads where some folks go out every year with a radar gun to see how fast they really go. (Like this post  : http://www.epicski.com/t/30993/how-fast-do-you-ski/420#post_1873841 ). So some of this is re-hash... 

 

Top speed last year (May 2015) was 71 MPH. That was reportedly on a relatively ungroomed slope, and the supposition was that they'd have seen much faster speeds on a better slope. In past years they've had folks in the 80s, including some who weren't on DH skis, and I get the idea from the threads that no one is wearing a speed suit.  

 

So it is possible - though also possibly dangerous - to go that fast.

Agree, GPS is going to be accurate most of the time.  But the issue with a max speed calculation is that it needs consistent data ALL of the time for your entire trace.  1 glitchy datapoint  is going to throw the max speed calculation out of whack since it's just calculating the change in position.

 

The GPS is going to have the hardest time skiing, as you're right on a rocky ice mountain, where there are reflected signals to throw off the gps.  Additionally there's no secondary signals like multiple cell towers and wifi for it to help with the gps calculations.

True, but it does show you all of the intermediate speed calculations too. If it's got a good positional fix along a trace, those should be accurate.

That depends on where you ski... I've had great cell reception some places, so I'd imagine it might be getting multiple towers.

According to the app my buddy Travis hit 72 on Anderson's the weekend before last.  He came into the top with a head of steam and straightlined the entire pitch.  It was groomed and crisp, I have no doubt the speed shown was correct.  (BTW, it was on pins, way faster than I'd like to go on Tele's.)

 

I'll have to get ahold of Endless and see when it's going down this season again.

pretty poor troll...:).   I make no claim to be averaging 83. It was simply a fastest speed recorded on the app. I make no claims to the veracity or otherwise of it.... And, as a regular, and fairly successful Masters racer, I am well aware of the difference....and also how you can max out top speed by straightlining the last pitch....;)

post #462 of 472

I am not a ski instructor.

I do not pretend to ski with such precision, balance and slope mastery as as ski instructor would...especially at speed.

But I would say I typically like to ski faster than anybody on any given slope at any time.

 

To even ask this dorkie question you must either really suck or suck worse.

Are you talking about the question "How fast do you ski?" If so, can't it just be curiosity? I know I've enjoyed this thread, and don't see ANY relationship to asking that question and sucking.

 

Do you think the guys getting out the radar gun and hitting 80 MPH suck? If so, that seems kind of ludicrous to me.

post #464 of 472

If you can do 80MPH through Wally World without killing someone then you can ski.

Just because one can do 70-80 in a straight line doesn't mean much about ability at normal speeds. The ability needed at speed in a straight line is to be calm, absorb the terrain variations, and use as little edge as possible. This is definitely a skill, but may not be present with other skills.

Hermann Maier liked super g because it had less gliding sections compared to downhill. He considered gliding at 70-80 mph boring, much prefering to rip out a turn on a pitch at 40-50 mph. Lol, he was the Hermanator after all.

I would agree with you.  But, all of the folks I've seen that are capable of keeping that calm terrain absorbing style are usually quite proficient at turning as well.

Don't. ScottSkier knows what he's doing and he knows speed on snow. I checked Ski Trax against the truck speedometer and it was right there.

It's a lot harder to ski slow than to ski fast. Just sayin'.

Is that a plug for skiing fast or slow?

Neither. Just an observation. And you can usually tell looking at someone if they're going fast because they want to or because they can't slow down. Also, as someone else mentioned--it's one thing to go fast on a wide open trail and another to do it while making the gates. (Watching the US National GS at Squaw on Dogleg a couple years ago I watched Ligetty wipe out. I've skied that run a number of times and never fallen, but then I wasn't doing 50 and trying to make gates. BTW--the racers thought that course was steeper and harder than any of the WC courses. It's also where the Squaw race kids train because of the steepness and because it's naturally very firm.)

True that.
