For me it isn't so much a question of pain, as you say pain is pain,
its a question of where do I stop? when do I say enough and then
what does that say about me in general.
Stopping can be slowing cadence on a flat, or climb or it can be
really stopping.
For me its the last 10 miles of HHH, cramping and my legs seizing but still continuing
even if it is at a snails pace barely ticking over the pedals (coz I know the legs are
gonna seize). Its the first 50 miles on a brooks pro saddle, yeah I know its gonna
get better, but it hurts now.
