Skiing Speed...

post #1 of 14
Thread Starter 
Hi Gang,

Just wondering if anyone can help me out.
I'm a long time skier and ski all types of terrain - mostly bumps, but do off piste chutes, and even cruising black/blue hardpacked and cord.

What Im wondering is what speed do I ski at?

Reading some ski reviews they say "they definetly have a speed limit of 25-30 mph" or "best above 40mph". Well that doesnt really help me as I cant really guage how fast that is.

If im ripping down a hardpacked black or carving down a freshly corded blue how fast am I going??

I've tried to compare it to motorcycling, cycling, roller blading, car, but it is such a unique feeling that I believe its very hard to determine even an approximate ski speed. I think you'd be influenced by so many variables such as lighting, snow conditions, terrain, temperature, pitch, proximity to stationary objects (trees) etc.

Just wondering...

Without a radar gun or some electronic means of determining your speed, you may need to measure off a length of a run, and time yourself as you go through it, and do the math to determine your speed. Maybe if you can find out the distance between lift tower X and lift tower Y. Or go about it the opposite way. If you have a NASTAR or Coin-Op race course, measure the distance, and straight line it, just to see how long it takes. The only problem with that, is that you need to accellerate from a stop, so your inconsistant speed will result in a skewed average (unless they'll let you come flying through the wand!).

Do you know any cops who can get a hold of a radar gun??

I once had to monitor skiers' speeds in preparation of an accident report, using a police doppler radar gun.
The run was a 'red' (equivalent US blue) with a pacy gradient. Skiers were generally going at about 30 mph max, with an occasional 40 mph.
From your description I imagine you'd be doing about the same - probably never more than 40 mph.
Makes you think that the world speed record-holder is exceeding that speed by more than 110mph.

A friend of mine was in a speed event this weekend. Stockli Stormriders, speed suit and some waxing. The radar indicated 67. With jacket he was down by 10.

Yoy hear people squaking about timing with a GPS ....... this can't be accurate can it? With vertical involved you probably couldn't get an accurate number.

I got one of these a few Christmas's ago and just hang onto it during a fast run to measure the wind speed. Cheaper than a radar gun and good enough for the ballpark speed questions we have. http://www.nkhome.com/ww/2000/instructions.html

it is fun

no brakes

I feel like I go really fast. I saw myself on video for the first time last month and I was sooooo sloooooooooow.

Tom, That Kestrel looks like one of the best toys I have seen in a while. It sure takes a lot of the variables out of the equation on sloped mountains. How fast have you measured yourself in calm air? ... Do you feel it was worth the pruchase and is it easy to use? [img]smile.gif[/img]

It's a fun toy to have. Best speed for me has been 58.7 MPH.

It takes less than a minute to get accurate tempuratures after taking it out of my pocket. Windspeed is displayed as current/average or Max since turn on.
Very easy to operate. Only 2 buttons - on/off & Mode that cycles thru the outputs.
Good sized display so it's easy to read.

Some of the other Kestrel models add barametric preassure, but that was more info than I wanted while on the hill.

So, was it worth it? - For me, yes because I like to know the real answer more than "man I must have been doing 80!"

GPS is pretty accurate... take it on the road and check against your vehicle's speedometer.

The problem with GPS derived speed is that it shows speed based on change in latitude/longitude over time. It ignores any vertical component, so the GPS speeds will typically be lower than surface speed.
Since roads are never more than couple of percent grade, this factor doesn't come into play as much as when skiing.
Plus, they cost more and are bulkier than the Kestrel.

Out of curiosity I did a quick web search looking for hand held radar guns and came up with this one priced at $260. I was expecting price would be $1000 or more. I'm not going to rush out and buy one but thought I would pass on the info.

SCSI Drive and I raced on International at Vail, and I beat him to the bottom with a top speed of Mach II.
Of course, my alarm clock then struck the hour, and I got up for work.

Suunto has come out with a skier specific wrist top(the S6) that requires no hands or attention to operate while skiing. It accurately gives slope inclination, rate of descent, max and average speed during descent, altitude, baro pressure, and a plethora of other functions as well as a log of all vert and laps done during the days sliding. Data is also downloadable to your computer. If you do a lot of b.c. trips or keep a detailed log it could be just the ticket. suuntosports.com

I predict a lot of disillusionment(yaayyyy) in the process of going from "Dude, like I was doing 70 and..." to the more likely, "45mph??!!! this *#%^$&@ must be busted!!" Or the "50 footer I dropped" turns out to be 17 feet high. Could be fun.
