WOw, week 5 I think since my back surgery...actually , i lost track which is a good sign!
I'm back on my bike outside (although my surgeon thinks i'm insane and thinks i should never ride a bike again probably).
OH My gosh does it feel sooooo good. I did 30 a week ago, three days of 20's and tomorrow i'll go for a 40+ if i can find enough roads that don't end up on supper highways!
"Oh to ride...along side...where the cows roam free"

That feeling we get?...I have always gotten a "high" from excercise. (my husband, just gets wiped out...how sad not to know that feeling!) There's an added bonus of feeling speed under you, feeling wind, and that ever so slight warped thrill of knowing that any moment you could be one with the pavement. AHHH...OUCH!
Definately something to Darwins' theroy ...for every action there's an equal yet opposite reaction. Wait, is that Darwin? or Newton? or Einstein?
Never could keep those guys straight!!!!
Instant results from your effort. And the more effort...the more wind!
Happy riding! and LOTS of wind in your face!!!
