Last week the major point that was noticed was to use the high tuck even on little downgrades and to double pole more and not use the ds as much. The short tuck will let you relax and drop your heart rate, while maybe saving you a couple of double poles.
Be sure to curve your back muscles a bit, too stretch them while in the high tuck.
The last class also reinforced the idea of switching your skis when the wax is worn off on the inside edge as it normally takes far less then 30 seconds.
Be sure to switch to the inside lane when safe to do so to take the corners.
Some points to remember this week.
Hands are held hip width apart, not shoulder width apart, dp and ds, in order to have the hands travel a straight path forward and back.
Elbows are wider then hands as in the chicken wing, and only you can decide how strong your rotator cuffs and deltoids are.
Too a point, the wider the elbows, the easier and faster you can apply gravity, core, body weight and muscle in that order, but you will need a slightly higher tempo, for the core is so strong.
Once again I must remind you that each movement explodes and then relaxes. If there is no relaxation phase then the muscles will not be flushed out in order to receive new blood.
First only you can to decide when to start using the herringbone(hb). Just because you can diagonal stride(ds) up the hill does not necessarily mean that you should. You have to think how much further you have to ski, how strong your arms feel compared to the legs, what kind of terrain still needs to be skied, and how many people will be in your way before you are done.
If the snow is loose you can lock the wax into the ski and not really use much of edge, which will be faster then hb on an edged ski.
"Increase both the angle between the skis and the edging on the insides of the skis. Move
the legs straight uphill, and increase the “V and edge the skis enough to maintain traction." as you go into the running hb. (CANSI Manual) Only widen your skis enough to not slip and keep your head looking up on the hill.
Do not let the hands get wide but turn hips and shoulders turn just enough that you are still planting the poles within 4-6 inches of you skis.
The hb movement and timing is the same as the ds, but with the skis a bit wider depending on the steepness of the hill.
Remember to keep your hands at around waist height and plant your baskets a fair bit further back which will depend on the steepness and your running hb speed.
The other point I wish you to remember is the when and where to use the running diagonal side step(rdss). Check the pole tracks first in case it has all the grip and control you need. Remember to use rdss on the uphill side of the slope and the tip should always be pointed towards the middle. It is used for passing a lot of times, as slower skiers will be hb up the middle of the trail in the #Birkie. You should also use it to save your arms.
Once again be sure to get out and ski for 5+ hours if doing the 55km.
Have FUN, stay healthy and uninjured!!
BRRR!! -25C with windchill, but if you stay out of the wind and raise the heart rate it was easily doable.
