Suffering is in the mind of the sufferer. To some, the act of breathing hard and sweating constitutes suffering. To me that state is a "state of grace". My body has undergone a transformation that the eternally sedentary can only imagine. I know from experience my aerobic capacity has doubled from my at rest state, the endorphins are coursing through my veins, and I experience a euphoria enhanced by the scenery and the sweet air I'm inhaling. Climbing allows this state at lower speeds, which permits me to relax mentally - as opposed to high efforts on the flats which lead to higher speeds.
Racing is a different matter. Digging ever deeper as we lead or chase the peloton, gritting our teeth and vowing to keep up with that wheel ahead- now that's suffering! When my heart is pounding so hard I'm afraid it might burst-that's when I tell myself-
today is a good day to die!
And by the way, that's the Tourmalet Eddie's climbing.
