Hmm, apparently I’m alone in remembering a century as something that is much more fun afterwards than during. Especially the last 25 miles.
It’s a leap from rides under twenty miles to going all day in the saddle. I remember thinking that if I sat down at the 78 mile rest stop I might not get up again. It is fun. I’m doing it again. But I’m not sure I’d attempt 100 miles without a few long range rides first. If I did, I’d have alternate plans for getting back if I decided enough was enough. And for what it’s worth, I’d make sure my saddle was the most comfortable one I could find.
