If you're an advanced level skiier who was bombing it down a groomer then you probably did hit close to around 80. Just bombing it on GS skis down steep blue/black runs with full clothing, GS skis and a little bit of aerodynamic effort without going full tuck (pulling in the arms) I can get to around a max of 80. But 95-100 is a whole different ball game that takes not only a concerted effort to get to, but a way bigger effort to maintain and be/feel safe. But yeah, as Ola says, GPS is far from perfect on a ski hill. The only way to know your speed for sure is either to use a two-point speed trap through a straight line or a radar-based one, which unfortunately neither one of which are generally accessible to the public.

Phone GPS is terrible for instantaneous speed measurements on ski slopes. I've tried most of the apps and almost all end up giving erroneously high readings for max speed which happens when they lose track of you for a moment as you move then the app assumes you didn't move then relocates you in the new location and uses the wrong time to calculate velocity. It works fine for driving but not max speed on skis. EDIT: This thread has made me curious and I'm considering getting a cheap radar gun to test out velocities of our skiers for fun.

Ski Trax says I did 51.6 mph (83 kph) last year at Northstar as I bombed the steepest straightest groomiest groomer on a Snowboard in full tuck. Whatever speed I was actually doing, I can't imagine going much faster than that because I was flying, but it's probably a lot better on skis since you are stable just pointing straight.

I was using a garmin watch with the ski setting so I assume it is a bit more accurate than a phone, and it was on completely empty perfectly groomed slopes and i was generally going for it, so I expect it was pretty fast, but I did think 95 was a bit much, I imagine it was more in the 80s. Average speed was much lower obviously, more like 35-40 km/h. Would love to find somewhere with a speed gun and have a test though.

I went back and looked at my tracking app to check max speed and I hit 85mph* last year. * On the freeway on the way home because I constantly forget to turn that poo poo off.

I grew up racing and have worked with GPS recordings in the context of sports for the last 6 years or so. Others have touched on this but most "max speed" values you're going to get out of a GPS app or device are going to be suspect for a few reasons: - instantaneous speed from GPS is generally not that good - even if/when it is, for any sensor data that has noise or inaccuracy, selecting the maximum value of that data stream is incredibly likely to just be selecting an outlier value caused by that error/noise in the data. If you can look at the time/location data points around where the maximum speed was recorded, and it seems consistent with what you actually did, then you can generally trust that the average speed over a handful of seconds comes close (assuming recording at 1hz, which is common). 50mph is totally doable just skiing around wearing normal clothes, if you're bombing down a steep groomer. Getting much higher than that is tough.

Funny coincidence, a pro biathlete just posted a clip hitting a dedicated slope with a speed trap. 104.95 kph in normal clothes. https://www.instagram.com/p/B8O0-OdpmUg/ Looks like a cool place to try it! If if think his comment is funny, it's a follow up to this: https://www.instagram.com/p/B8JzCGfJdvD/

Ola posted:GPS on your phone can be very accurate. Particularly in a car because it correctly assumes you are in contact with the surface on a well mapped road,so it can snap to the most likely position. When testing my phone against speed warning signs on the road and it's accurate to the whole digit every time. You greatly over estimate the accuracy of GPS, especially in mountains where the signals can be blocked and/or bounce off the mountains. Similarly when you drive in the city and your phone GPS will freak out.

Eejit posted:Wasn't it like 6? years ago that FIS mandated super long, virtually-no-sidecut skis? Well it started I think 7 years ago (the year before I started racing FIS) but they're still basically super-long with no sidecut. Women's DH skis are now >210cm with a 50m radius. SG are >205cm with a 40m radius. GS are >188cm with a 30m radius and slalom is the same it's always been. They did drop the men's GS from 193 >35m to being the same as women's (I think) because those numbers were ridiculous for 16 year old boys. I am going to be glad to be able to pick my own ski length and radius again starting next year when I'm not racing FIS anymore.

Whiteface is claiming 20 inches on their twitter page. Probably less, but still the best snow Adirondacks have had in a while. Too much for some stuff; https://cbs6albany.com/news/local/weather-conditions-prompt-avalanche-warning-for-adirondacks mountain-forecast is saying windchill at the summit of WF will be close to -40 tomorrow, so hopefully that keeps the crowds down.

My Dudes and Dudettes, Being a gadget loving dumb rear end I was going to buy some X socks and give a trip report on them. I visited their webpage and it turns out, they want like 40 loving dollars for socks. So I will not be able to give a trip report unless I get drunk enough to spend 40 bucks on socks. And I don't know if I have *ever* been that drunk.

Honestly it's not bad as long as you're west of Golden by ~6:15. The problem anymore is the lift lines. I was getting about 2 runs an hour in yesterday and that was putting me about at my limit (10-15 minutes wait per lift, which is interminable as a soloist). Sooooo many groups of people jumping in the singles line. Which I wouldn't be grumpy about except they invariably gently caress up the grouping as they surreptitiously try to ride together.

Totally fair but I do prefer walking up at 7, breakfast and coffee, free bus to keystone. Really though I ski way more in the backcountry these days.
