One randonneur (from Pennsylvania) replied in part: "I have decided I'm going to keep riding long distance until I have a ride where I don't hate myself sometime during the ride."
Although that was the flippant portion of his reply, it made me pause and think, and this is what I noted in response to the immediately above [I've made four edits from the original]:
I've hated my bike;
I've hated bicycling;
I've hated randonneuring, sure that it was invented solely as a torture device / method.
I've hated the pain in each of my buttocks;
I've hated the pain in my lower back;
I've hated the pain in each of my feet, calves, quads, hands, and in my right tricep;
I've shed tears of pain because of an extremely painful tendinitis in my right leg;
I've yelped due to the pain as my shorts tried to whittle the end off ... something.
I've hated the rough road;
I've hated the look of the next climb;
I've hated the never-ending FLAT road.
I've been "fed-up" with the person(s) with whom I was riding;
But I've never hated myself (while cycling).
Maybe if / when I ride something beyond a 600?
