It's amazing to me the amount of useless data I can generate in my mind on a 80 minute ride.
Up until 2 months ago I used to wear a radio on every ride.
Since then the ride has become a peaceful and quiet time for thinking, meditating and getting into all that is going on around me.
The bike, the road, the cars, what's up ahead, what's behind, my spinning, my cadence, my speed, my heart rate, my breathing, up shift, down shift, stones, glass, shift hand position, relax elbows, my ass, blow my nose, take a drink...
