Sprinting: Slowing Down to Go Fast?
Sprint racing can be a tough balancing act, between tempo,
technique, pace, and power application.
As the sprint courses have grown in distance and time, not only on an
international level but also domestically, controlling your tempo has become
more and more crucial to laying down the fastest time of the day.
People automatically associate sprint racing with moving
everything at top speed to try and maximize speed, however, if you focus
more on big powerful movements you will always beat the racer flailing in every
direction imaginable. This proves the
contradiction: slowing your tempo down to apply big powerful explosive
movements will be faster. To the average
viewer it will always look like the flailer will be setting land speed records
but it will be the smoother skier always coming up with the fastest times. Don't get me wrong though, you can't go
through the entire course with the same tempo. The terrain will always
dictate what tempo is the fastest.
Sprint courses will generally have some steep climbs and some
gradual sections. It is on these gradual
ups and downs where you can really maximize your speed with tempo. These gradual sections were made for skiing
big. By slowing your tempo to maximize
the power application of the technique you will maximize your glide and
increase your efficiency. If you kept a short quick tempo through the
same section, you would have doubled or tripled the number of strokes as the
same racer skiing big. Now as the race
continues and the gradual section of the course leads into the steeper
sections, the slower tempo racer can now shift gears, quicken the tempo, and
accelerate up and over the terrain. The higher tempo skier simply has to try
and maintain the same high tempo into a section that is much tougher than the
previous gradual section often leading to deceleration and fatigue. Every transition in the sprint course terrain
can be thought of as a cue for a shift point to dictate a change in your
tempo. By continually changing tempo
to adapt to the terrain you will be skiing each section efficiently and
quickly.
Sprint racing is just a much shorter distance race really. The racer who covers the course with the fewest amount of strides will have
skied the most efficiently and covered the most amount of ground in the fastest
amount of time, every time. The flailer may look the fastest but wasted
movements equal wasted energy, resulting in fatigue, which kills your speed. In a game where you want to reach your max speed and pin it there, you need
to ski as efficiently as possible.

WAX RECOMMENDATION Yellowstone Rendezvous Rendezvous Trails, West Yellowstone, MT Saturday March 6th, 2010 9:15am Start Technique: 50K, 25K Freestyle & 25K, 10K, 5K, 2K Classic
Forecast/Conditions: Friday Night: a slight chance of snow showers, mostly cloudy, low around 6F. Saturday: A chance of snow showers in the am, mostly cloudy, high near 37F. Expect snow temp at the start around 8F. West Yellowstone snow is typically dry & abrasive. Expect partially transformed fast and hard packed snow.
Glidewax: Apply LF Moly/LF Blue mix, scrape and brush, then apply HF Blue, scrape and brush. Finish by rotocorking JetStream Blue, brush with a dedicated nylon polishing brush and polish with a thermopad.
Gripwax: Roughen base with 150 grit sandpaper, iron in Carbon BaseWax Green, cork smooth, let cool. Then apply 2 layers of Carbon GripWax Viola followed by 2 thin layers of Carbon Grip Blue, corking smooth between layers. Check TOKO Wax Recommendation easel prior to race start and adjust as needed. Another solid option would be a very thick and short (klister zone) application of Base Green binder (only).
Structure: A fine linear structure will be good. One good pass with the Toko Structurite tool with the Blue bit before applying the JetStream is recommended.
Check the WaxTip page at www.TokoUS.com before all of your races for the latest waxing information. The Toko Race Wax Tips offer racers precise waxing advice on how to make your skis perform optimally for a given event. For racers who don't have top end waxes, skip the Fluorocarbon (JetStream) and substitute the LF or System 3 wax of the same color (Yellow, Red or Blue). For those who do not have a rotocork for applying JetStream, the next best thing is to iron it in. Toko Racing Service
