2018 Sierra Ski-O : Round 2

February 10 - 11
Lake Tahoe, CA


Update 2/4: CANCELLED - Unfortunately because of snow conditions we're going to have to cancel both races next weekend. The next week is going to be quite warm, and even if the ski areas are able to stay open through next weekend, there will not be enough of a trail network to make interesting ski-o.


Sat, Jan 27

11:59 pmLast day to register and be guaranteed a loaner Touchless SIAir timing chip. The club has a bunch to rent you, so they may still be available after this date, but if we'll need more we need to know here.
