Prior to this summer of biking, I cannot say that I have really been much of an athlete my entire life. I have started biking to work once a week, and just before the end of the ride there, there is a huge, steep hill that just about kills me every time. It is getting marginally easier, just because I know I have done it before, I think. However, the last couple of trips up the hill I have felt what I *think* are my endorphis kicking in! I have never experienced that before, so I am not sure! I feel sort of a rush, but I thought your endorphins were supposed to help your performance - my hands and feet get all tingly and I sometimes feel like I am going to fall off the bike.

So - when do your endorphins kick in? What does it feel like?
Thanks!
