Thomas Alsgaard comments on technique...

I asked Alsgaard what was the most critical things to focus on as far as
technique that yield the most speed. His answer: "go by feel..." he went on to
explain that people tend to focus on minute technical components of proper
skiing technique whereas he believed that the best way to improve technique is
to ski and vary cadence and skate stokes subtley to see what works best for you
(and the best way to test this is to ski behind someone of equal ability and
try different technique modificaions) He stated that he did not believe that
there was one best technique, to focus on what makes YOU go fast...keep the big
picture in mind and dont get lost in technique details and minutia....I found
it interesting that one of the best skaters in the world was basically
suggesting something I had also decided years ago...that I would try to figure
out what works best for me by going out and trying to vary my technique
slightly in different situations to see what works best and not to be over
concerned about using "proper" technique suggestions  when they dont seem to
ake me go faster...perhaps Potter had this right all along...its all about
maintaining momentum down the track in a way that works best for you....
