2018 City of Lakes Loppet Freestyle: Sunday February 4th
Race start time is 9:00 am with a forecast temperature of 0 F rising to about 6F at noon.
At these temperatures a hard wax like Swix CH4 or Start Green would have the lowest friction during the entire race. Start Green has been consistently faster than CH4 in our testing at these temperatures.
The chart below shows the forecasted temperatures in the black line with the scale on the left. The predicted coefficient of friction for 6 different waxes is on the right hand axis. The fastest wax will be the one with the lowest coefficient of friction
The chart below shows the estimated time lost due to using a sub-optimal wax.
Start Green is the fastest and so has zero time lost. Swix CH4 is estimated to be about 1.5 minutes slower for a skier with a finishing time of 2 hours. A blue wax will be about 6 minutes slower at these really cold temperatures.
