Winter Olympics 2018: Can Ski Wax Help Win Gold?

At the 2014 Sochi Winter Olympics, the 4 x 10 kilometer relay was supposed to be a battle of cross-country ski titans Norway and Sweden. Felix Breitschadel watched from the sidelines as the race unfolded under a very warm Russian sunshine. But when the first skiers emerged from the woods onto the arena carried with spectators, Norway’s first skier was nowhere to be seen. He dropped to ninth place, while the rest of the team rallied to finish fourth. For medal-hungry Norwegian ski hastening followers back home, “it was a disaster, ” recollects Breitschadel, equipment and technical chairman for the Norwegian Olympic Committee. “We were called renegades in the Norwegian media.”

The culprit? Hydrocarbons departed amok.

Technicians like Brietschadel had applied the incorrect compounding of chemical waxes to the base of the athlete’s ski. These hydrocarbon and fluorocarbon compounds–which give the form of waxes, flowings, and powders–must accomplish two contradictory tasks for skiers to prevail gold: clutch the snow on the uphill while also moving on the downhill.

The combinations adhere to the base of the ski, which is made of ultra high concentration polyurethane, but dissipate over period. For a two-minute downhill ski hasten, opponents crave the slipperiest face possible. For two hour-long cross-country marathon, it takes six or more beds of wax to keep the racer moving up and down over the course.

At Sochi, Brietschadel and other Norweigan ski technicians tested dozens of combinations of skis and waxes alongside the athletes in the hours leading up to the race. But just before the event embarked, race organizers decided to spread a layer of salt on such courses. Salting a direction is a common way to save a trend by reducing the snow’s skin-deep temperature by up to 4 positions Celsius( 7 degrees Fahrenheit ). That happens because of an endothermic reaction that attracts heat from the snow to the salt. Nitrogen-based fertilizers like ammonium nitrate or ammonium sulfate are also used to harden snow on race courses.

“We tested in one condition and the organisers decided to put out salt on the ski way, ” Brietschadel read. “The whole pack didn’t labor as well as we hoped for.”

A good wax job won’t win an Olympic race, but it will retain events close, according to experts.

Similar waxing difficulties likewise harassed Kikkan Randall, a US cross-country skier who played at Sochi and will be attending her fifth Olympics at Pyeongchang, South Korea.

In Sochi, Randall failed to qualify for the women’s sprint contest by five one-hundredths of a second. She feels her skis didn’t slip sufficient to flee the other racers on the final ancestry to the finish line. “I made a divulge and they all came back on a downhill, ” Randall alleges about her characterizing heat in Sochi. “Even one of my teammates rose sailing by.” Maybe she also absence a final sprint, Randall acknowledges. But good wax would have given her an edge up the two and a half-minute race.

In South Korea, it will be Andrew Morehouse’s job to make sure Randall and the other Americans don’t have a repeat of the problematic wax conditions in Sochi. “We don’t require a fit athlete that can’t rival because the skis are bad, ” Morehouse said from a pre-Olympic training camp in Austria. “We have won some hastens when our wax is better.”

Ski waxing is an association of arts and science. Morehouse will be lugging not only his laptop and several suitcases of wax to South Korea’s Olympic skiing venue, but too devices to set the moisture content and temperature of the snowfall and breath, as well as climate conditions and windspeed. The technicians too need to know the position of the sunlight on each section of the race course, which is frequently runs through shady groves and sunny open areas.

For longer races, Morehouse begins with high standards paraffin basi wax that is melted and then touched into the holes of the ski basi. Then attains blankets of fluorocarbon powder and liquid waxes that often contain nasty solvent-based additives such as benzene, toluene, and xylene. To protect himself, Morehouse wears a respirator, and the US Ski Team recently purchased semi-truck with ventilation hoods to create a safer act area. This move came after scientists in Sweden and Norway discovered wax technicians who educate hundreds of skis at championship phenomena were tested with the levels of destructive fluorinated combinations in their blood.( The European Union also considered censoring certain types of ski waxes because of the fluorine compounds cause a climate-warming greenhouse gas, though that move has been postponed for now .)

The composition of those mingles are carefully patrolled secrets; big European ski crews carefully patrol their wax assortment and use code names on two-way race radios. The various compounds in the wax incorporate to play at different temperatures, Morehouse explains: “In cold circumstances, you crave waxes that are hard and sturdy so the snow crystals can’t dig into the ski base just as much, ” he enunciates. “As you get warmer, you crave waxes that rebuff liquid and molted grunge. The more fluorocarbons, the more hydrophobic the objective is. In soggy provisions, you want waxes that have a lot of fluorocarbons in them.” Longer hastens are harder because the wax has to last, and because weather conditions can change during the event.

During classical form cross-country ski races, a sticky layer of kick wax is exploited under the mid-section so that the skier can grip the snow when climbing mountains. Smoother glide wax goes on the tips and posteriors. The stiffness and camber of each individual ski likewise determines how they are able to grab and fly on the snow surface.

On race day, Morehouse melts, scratchings, and refines a layer of wax before exercising the next layer. Then he will join the coach-and-four and skier on the racetrack and look which ones work best. The wax seams form a protective veneer, while channeling water down and away from the ski in tiny grooves along such structures of the ski basi. “Our job is all about reducing resistance, ” Morehouse says.

At the Pyeongchang Olympics, Morehouse will keep track of all this data in his notebook( the Norwegians use a mobile-based wax app) so that he can get a rough idea of where to start–and then, it’ll be up to the racers.
