I'm jealous as usual of your indoor track work and training partners...the Y we belong to has a 20 lap indoor track...I've never seen it or used the Y...mostly Chrissy does and James occasionally...anyway those quick reps and miles are impressive.
You've probably talked about your racing heart, but what did you learn from your doctor about it?
My 'chest thing' is more a discomfort and racing and only occurs when in running motion...I'm going to bring this up with doc when I have my physical on Feb 9th I believe.
Saw on Weather Channel website -19 there with -37 WC! That's the stuff of winter 71-72!!! I'm losing my toughness against cold...it's in my mind again. When we moved to Duluth I had never been in zero cold and thought life ended at that temp...47 years later I still have some of the ole Finlander blood left from living up there and going through 3 though winters, but this year I don't look upon the cold as challenge...I'm only trying to survive and don't feel tough at all.
