So I finally rode 100 miles yesterday. I've been working up to this all through September - riding 100miles each weekend (some on Friday, Saturday, and Sunday = 100miles) shifting the weight toward longer and longer portion on Sundays. I'm feeling OK, knees hurt a bit, which is new, but otherwise OK. I'm thinking I'll get a saddle with a center cut-out before trying it again. I stopped to rest at about 70miles and actually fell asleep for a half hour. Totally unconcious. I woke up, shook it off, got back on the bike and finished up. Took me 6hours and 13 minutes of riding. Anyway, I just had to share. Feeling pretty good for doing it.
