And it can tell you other things like max speed during the day. Very amusing stuff. If you have a Garmin mapping GPRS, I have a map of the 3 Valleys you can load into it. It has all the lifts runs and First Aid posts, and most of the mountain restaurants as well. Its home-grown so there are no copyright issues - shout if you want a copy. Walter |

Walter I don't have a GPS yet but I would love a copy of the map for when I do. I have also been toying with the idea of setting up a resource for GPS Piste maps, Home grown maps would be great. |

... I have a very accurate map! The distance is exactly 62.5 miles well done guys! But, is that taking into account the ups and downs? If not, one should add 10-40% to the distance depending upon the gradients of the slopes traversed. |

If not, one should add 10-40% to the distance depending upon the gradients of the slopes traversed. Nothing like. Add at most 5 or 6%. If you are skiing on normal pistes with a mix of blue/red/black you are unlikely to exceed a 20 degree gradient on average over the day. 30 degrees would be an extremely steep black. It doesn't sound like a lot, but I can't think of a marked piste in the 3V that exceeds that (including the couloirs in Courchevel). |

And yes, this would be a steep average for a day. -- Ace (brucedotrogers a.t rochedotcom) Ski Club of Great Britain - http://www.skiclub.co.uk All opinions expressed are personal and in no way represent those of the Ski Club. |

And yes, this would be a steep average for a day. I think we may be talking at cross purposes here - the % I mean when I say 5 or 6% is the amount to add to the horizontal distance travelled to get the "true" distance covered - I assumed this is what was meant by "helloblondie" when suggesting adding 10-40% to the distance. I.e. if you measure the distance on a map I think you need to add about 5% to the figure to give the actual distance covered to include the extra due to going up and down. Of course if you did speed the whole day on super steep runs you may need to add more. Either way, a 15% or 30 degree slope is steep in any language:-0 |

That's exactly what I assumed. I.e. if you measure the distance on a map I think you need to add about 5% to the figure to give the actual distance covered to include the extra due to going up and down. Of course if you did speed the whole day on super steep runs you may need to add more. Imagine the horizontal, or map distance represented by the base of a triangle, whose hypotenuse would then be the distance travelled over the snow. Schoolboy geometry tells me that the cosine of the angle between these is equal to the length of the base divided by the length of the hypotenuse. So if I ski 1 mile at an average slope of 30deg, the actual distance skied would be 1/cos30, which is 1.15 miles, a 'difference' of 15%. Hope it's clear now. -- Ace (brucedotrogers a.t rochedotcom) Ski Club of Great Britain - http://www.skiclub.co.uk All opinions expressed are personal and in no way represent those of the Ski Club. |
