Type-2 Fun is a genre of pleasure that is experienced after partaking in a particular activity. Type-2 Fun is doesn't seem so amsuing or pleasant at the time, but once it's finished, is retrospectively amazing.
Most endurance athletes, especially cyclists LOVE Type-2 Fun. There are other sensations of contrasting comfort and discomfort specifc to cycling that have offset timing:
One is the pain of crashing. Hitting the deck in a race never feels good. Usually it takes a few moments of contemplation on the ground to figure out just how "not good" skidding across the pavement felt. Personally, my brain knows something unpleasant happened, but there's a solid disconnect with the rest of my body that refuses to give it any further information. If my head didn't get slammed, and my extremities can still move, I usually get back on the bike and do what I can to pretend it never happend. (The trick to success here is not looking at ANY part of my body that may have road rash. In that case my brain would be bypassing the message-firewall that my body set up. Seeing is believeing, and I don't want to see that torn up mess of bloody skin until the ride is over.) The offset-timing comes into play the following day. That's when the pain, stiffness and tenderness peak.
Another sensation with funny timing is caused by extreme cold. I got stuck in a slushy muck of a snowstorm riding up in Nederland, Colorado today. I'm here for altitude training, and the weather is hit-or-miss at this time of year. I headed out for some intervals in a misty fog, planning to be back an hour before the snow was scheduled to fall. The snow fell early though, in a sleety mess. The final battle home was a character-building session of self encouragement blurts, dismissal of doubts of survial, and strategic rotation of finger positions: a couple digits were always in their glove-holes, ready to brake and shift, while the others huddled together, folded into my palms, warming up for their next shift of duty.
The real pain on rides like these ironically comes back in warm, dry shelter. As my fingers and feet finally thawed out in the warm shower, I instinctivley stomped around the tub's floor trying to dissipate the pain from my mind. The thawing itself was more intense than any sensation on the entire ride. It was excrutiating and I waned to cry. I'm going to think of that pain to put things into perspective the next time I have VO2 intervals to do.
Enjoy the ride, and the collection of feelings that come along with it before, during and after.
