One thing that complicates the situation is that for me, part of the fun of riding is the feeling of accomplishment when I'm done- especially true on a longer or harder ride. Then also, even during a ride, you can have some things that are fun and some that are not. So I've ridden into a headwind with sore feet and a saddlesore, but was also in the company of an attractive and friendly lady, so who's to complain?
