Winning combination?

  Wind and cold...NOT a winning combination in my book. 
  I'm really trying to NOT get myself all freaked out about the upcoming 10K Saturday, but when the forecast came out and is predicting 39 for a high and 20-30 mph winds I tend to get a little nervous.  I have trained lots for this race, hit my pace many a time and done all I can to be prepared, but not sure I can prepare for that.  My first fault is that nearly all of my training has been on the treadmill, and the switch to the road has been a wake up call.  I definitely need to find my road legs.  My recent runs have left me less than sure about my confidence level.  I've had a few great ones, and few that leave me wondering why I am attempting my first 10K so early in the season.  (I've run the distance plenty, but the outside pace seems so different) 
  The wind is what is really scaring me.  I am a total fair weather runner.  If the wind is over 10mph I opt for the TM.  The race is right off the lake, so the certainty of lake wind and cold is 100%.  I may need to reevaluate my time goals.  The good news is that since this is my 1st 10K, I'll surely be giving myself lots of room for improvement in future ones.  LOL.  I will try to be calm and see what the day brings, but YIKES I'm getting nervous!!
