Typical speeds in SL and GS

post #1 of 9
Thread Starter 

Does anyone know the typical speeds WC racers travel at in SL and GS?

 

No reason really, just interested!

post #2 of 9

40-45 MPH in GS

 

30-35 MPH in SL

Atomicman as far as I know, they are much much faster.... if I remember right, normal speed in GS is somewhere between 80 and 90km/h (around 50-55mph I think). For SL I forgot this data, but they are faster then 50km/h (30mph) for sure.

Primož, at what level though?

I guess Narc was asking about WC racers. WC is World cup for me, but I appologize if I missunderstood this, and Narc meant something else with WC.

My error, didn't see the "WC".

Maybe if they use weird ski speedometers.

 

Assuming we are talking about AVERAGE speeds, I think it is more realistic to think in terms of 70-75km/hr in GS and 35-40km/hr in SL.

I did a calculation for my team the other day based on 35mph which is the consensus I gleaned from a google search.

 

At 35mp that is roughly 55 feet per second.

So 1/10th is about 5.5'

1/100 = about 6 inches.

 

Obviously the faster the speed, the smaller the diff in ft/m.

 

Where can you find another 6 inches?

Average speeds top-to-bottom are a known figure for World Cup (and other sanctioned) speed races, because the results include the length of the course.

 

Recent Sestriere men's SG: 85 kph (best) - 82 kph (mid-pack) = 52 - 51 mph

Val d'Isere world champ men's SG: 80 - 76 kph = 50 - 48 mph

 

This, of course, includes getting up to speed at the top of the course, which pushes the average speed below the "typical" on-course speed, though not by a ton. Even if you figure it takes 200 meters to get up to speed, this would only increase the typical speed to 85 - 93 kph (58 - 53 mph)

 

To try to derive GS speeds from known (approximately, anyway) SG speeds, you can either reduce based on the apparent difference in speeds observed -- GS is noticeably slower -- or try to adjust for course length -- trickier: both the races noted above had GSs run on the same hill, and in each case they were about 30% shorter in terms of vertical ... but how much longer is a GS per unit of vertical because of the extra turns?

 

Anyway, I think the 40-45 mph figure is in the ballpark for GS speeds. The estimate of 50-55 mph is clearly too high.

 

Incidentally, the official FIS results sheets include a figure for the distance in meters by which each racer trailed the winner, which is apparently produced simply by applying the racer's average speed to the time he finished behind the winner.
