Hey Bluetree... looks like you got a lot of really great advice here and from your coach.
Here's that quote, if you wanted it:
From Zia_Cyclist: Another aspect of mental training is recognizing the difference between pain and suffering.
Pain is an acute, hurting feeling that if you don't stop immediately will lead to injury.
Suffering on the other hand is that feeling you get when pushing your body to the limit. Don't get me wrong, it hurts. But, suffering isn't going to lead to injury.
When I read about this and learned the difference it lead me to push harder on some of my long runs and in races.
"Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather, to skid in broadside thoroughly used-up, totally worn out, and loudly proclaiming: WOW WHAT A RIDE!!!!"
