Thank you much, in my training for it, Sat. is my long distance ride day. This past Sat. I rode 43 miles with the legs (thighs) being a little sore towards the end. You have any advice for during the Centry ride? I know there is going to be some discomfort there with the ride. Its not every day that a human gets on a bicycle and rifes it for 100 miles, even the body is smart enough to know this.
