Updated Friday, 2PM:
The snow that is currently falling is fine dry powder. Perfect if you are a snow boarder or downhiller. Perfect for cushioning falls on the famous bobsled run hills of the CSM. Not so perfect for firm tracks. But you can't have it all.
This snow won't change the glide wax, but you might need a bit more grip than Carrot or K19. Add a layer or two of K15 under foot before the K19 or add some Tar Minus before Carrot. These extra soft/tacky waxes allow your grip wax to better grab the fine snow. Be sure to cover that with the colder wax to prevent wear and drag.
Best of luck to all!
Looks like the weather gods are smiling on the CSM skiers this weekend! Fresh snow, 5-15cm, enough to cover up any icy spots but not so much that skier will be up to their knees either. The temperatures are also favourable, low Friday night of about -20C, which will help firm up the grooming, then warming up to -9C and sunny Saturday. Back down to -16C overnight, so the CdB skiers can brag about the cold night, then warming to -7C on Sunday again under sunny skies. That's near perfect!
To go along with the perfect weather you need perfect wax. So here's what we guess (since we are not on site testing) will work well.
Base layer: LF Graphite or Molybdenum
Top Layer: HF Green + Gold Fox
80km a day is a lot for grip wax to withstand, so a thin binder layer is a good idea. With the big melt and rain last week I suspect the trails are firm to icy right now, even if they have been renovated. Since there is a good deal of fresh snow falling, a grip wax rather than a klister binder should do the trick. After that you will need the usual grip wax layers. We think the new Vauhti Kline would be great over the varied snow of the CSM course.
Binder layer: Base binder Super - ironed in, cooled and corked smooth
Top Layer: K19 or fluoro carrot
Best of luck to all CSMers!
