This is a skate or classic race at Snow Mountain Ranch near Granby, Colorado. It is high altitude Colorado snow. The current NOAA forecast for Saturday March 6 is:
Tonight: Snow likely, mainly after 11pm. Mostly cloudy, with a low around 20. East southeast wind between 5 and 7 mph. Chance of precipitation is 60%. New snow accumulation of less than one inch possible.
Friday: A 40 percent chance of snow showers. Mostly cloudy, with a high near 34. West wind between 11 and 17 mph, with gusts as high as 28 mph. New snow accumulation of around an inch possible.
Friday Night: A 20 percent chance of snow showers before 11pm. Mostly cloudy, with a low around 14. West wind between 10 and 13 mph becoming calm.
Saturday: Mostly sunny, with a high near 46. Calm wind becoming west northwest around 5 mph.
Talking with the folks at the nordic center, the weather has not been following the forecasts with consistency. There was snow forecast of Saturday and it has been moved up to Friday. It could be sunny or it could be cloudy with a chance of snow.
Skis: Pick a pair of medium to medium soft skis with a medium to finer grind. If it looks like it will be sunny and warmer, add a medium interupted pattern with a Toko rilling tool or the finer or red linera roller on the new Toko Tool. Rill after wax and before fluoro powder application.
Base wax: I would start with a mix of Solda UF7 and Solda Performance Green 50/50. Follow up with Solda F15 Violet. If it stays cold, below 24, go with Solda F31 or F40 Violet. If it warms and race temps are between 23 and 30 and the snow is transformed (not new) go to F31 Orange. If there is new snow, and it is between 32 and 18, go with F31 Pink.
Top coat: Again, watch the weather. If it stays colder than 24 go with Solda HP05 or the HP05-S30 mix. If it is warmer and new snow, go with Solda HP04.
If classic skiing, apply a binder to the kick zone. I like one of the following: Rode Black base, or Toko Green base, or Swix VG30. Iron it in, let it cool and then cork it smooth. I would start with multiple thin layers of either Rode Fast Blue Super or Swix VR40. After testing adjust up in temp it need be.
