Dude, you win with this one.
I've done some long rides, but they were also long ago when I was young and didn't sleep. San Fran to Austin, 26 hours. Virginia Beach to Cape Canaveral (to watch a Shuttle take off) then to Austin- 60ish hours, but I took a nap.
Anymore, the longest I'll do is about an 800 mile day. I guess I could get up early and put in 200 more, but what's the point? I like sleep nowadays. And coffee.
Anyway- if you decide to run one of these, take some aspirin with you.
