Top Speeds true or false? - Snowboarding Forum

SnowMotion · 03-04-2012, 11:53 PM

With all the smart phones and apps out there everyone is getting there top speed. But I feel some people are looking a kph instead of mph b/c I have heard some people throw around speeds in the 60's. My top speed at 6'1 230lbs on an icy east coast trail was 57.5 mph. I thought that was fast untill someone half my size said they hit 63mph. So if you know your real mph top speed share it and let's have a online race. Honor system remember your only cheating yourself...HA

Lol last GPS track said my top speed was 1900 km/h... I love my GPS tracking software (trekbuddy stores .gpx files that I upload to garmin connect), but it has to be taken with a grain of salt. Pretty much every day I'm on the slopes I have a few corrected peaks in the 70-80 km/h range, but I don't consider it valid unless it shows a steady speed instead of just a peak.

Besides, I'm way more interested in seeing where I went on the hill, and looking at my total mileage and vert.

I wouldn't worry so much about top speed. I'm not running gates on my board (anymore) so it doesn't really matter... At the end of the day it's how dead I feel and how big the smile is on my face.

I've tried using a handheld GPS that gave real time speed, but didn't record top speed (ie; you had to look at it on the fly). It seemed to give consistent readouts. As I recall, consistent reads were; carving a green run : 27 mph (easy to watch the GPS), carving a blue : 37 mph (harder to take eyes off run to see GPS), carving a black : 47 mph (could barely spare a glance at that speed), faster parts of the black : ?? (couldn't spare a second to look).

It matches dead on with a car's speedometer, too. Seems accurate on a plane, too. Pretty cool to see exactly where you are flying over...at 40,000 feet and 540 mph.

Ski tracks seems to be pretty accurate\conservative in it's readings.

Some science minded guy is going to comment about how your size and weight don't matter when it comes to speed. Board length and wax matter more.

Size and weigh definitely matter more than anything.

Roll a boulder and a pebble down a hill at the same time and see which one gets to the bottom first.

hmm, I wonder what the factors are. Drop them from the same level and they fall at the same rate.

I'm not a physicist but I'd wager a gentleman's bet that a rider's weight is really not very significant; most of us can "point it" and straightline conditions that would destroy a novice rider no matter his size. Board length, snow conditions, wax, rider ability, etc., are probably all more meaningful than weight/mass.

Also, I have heard that these handheld GPS and especially the apps in your smartphone really don't provide an accurate measure of speed in three dimensions; that is, they perform reasonably accurate while tracking your vehicle speed on a (relatively) flat surface street or highway, but once you put yourself on the snowboard at a 30- or 40-degree incline its nowhere near as reliable.

Case in point I saw someone say their crazy friend hit like 73mph on a Never Summer Evo. I call bullshit on that. 73mph is approaching olympic GS speed (~80 mph) there is no way anyone on this forum is doing that on an Evo. So, take these speed things with a grain of salt.

This is only true in a vacuum but I still don't think that the pebble/boulder thing is a good comparison.
