Ski GPS

At last some one sensible , thanks guys I've enjoyed the thread.

That does underline something I was trying to point out above, ie they're not very accurate. A recreational skier wouldn't really get much over 40 mph in reality, if a GPS device is saying significantly more then it's not accurate. Speeds around 60 mph are going to need at least GS skis and probably a cat suit.

Someone did try this out comparing a GPS to a real speed gun and the GPS was producing speeds like 60mph which the speed gun showed to be more like 40mph. In fact 40mph is pretty fast really.

As a perspective, at top level racers would be moving at a maximum of 80mph or thereabouts, speed skiers obviously rather faster. Even that tells a story though, novice speed skiers tend to struggle to break the 100kph on initial attempts so 60mph on piste would be quite extraordinary.

Unfortunately, hey're a bit of a con these devices, GPS simply isn't an accurate device to measure speed over short distances in the mountains.

I agree with ise about the potential for inaccuracy with the GPS measurement. I do have beg to differ about the speed of recreational skiers. I'm one, and I found it pretty easy to hit 51mph (83kph, Longines Timing), using a pair of rather tired rental skis. From the way it felt, I know there have been occasions when I have been somewhat faster.

Jeeeeez, how 1980's are you?

Seriously, you can pick one up for about the price of 2 fantas in resort in France.

The cost of purchase is not the deciding factor for me :mrgreen:

As for being 1980's...you have no idea :lol:

If it a longtines I presume it was a closed course? Which was really my point, on a piste it's not very likely

Closed, in so much as folks were crossing it on skis, yes. You have to wonder how some folk reach maturity :lol:

My point is, this is the only time I have been on a decent timed run and I know that before and since I have been faster on my Stocklis particularly. I spent many years riding motorcycles and I think it helps to judge speed/wind pressure on the bod. Having a nice smooth surface to ski on helps naturally, with only the occasional set of tracks to cross )

I dread to think what speed the woman who hit me and broke my collarbone was travelling at, suffice to say my collarbone was broken before I hit the ground. By the time I touched down I was generally out of it anyway.

Anyone who has let them go on the Trolles black run down into Tignes Le Lac will know what speed on skis feels like - I've not idea how fast you actually get up to and Ise is probably right - not as fast as you might like to think .....

..... but, as you pick up speed schussing down that hill, praying that you don't catch an edge, absolutely crapping yourself, it feels like a 100kph+ :shock: :shock: :shock:
