What's the fastest anybody has completed a century?

[Archaea]

For me, I haven't done any too fast, as in one I was with my wife, in another with a buddy and others some gals. So I had to go back and help.

My wife to her credit had never biked more than forty miles before her first century, and tooled along just fine. It took us about "seven" hours. Which is fine for her. We didn't paceline or anything. Because it was with my wife, it was worth it. With my buddies we tooled along in about 5 h 30 min. Again I had to go back for them.

I've always wanted to torch one. My buddy did Tour de Tucson in 4h22 min. I was impressed but would not have stayed with him.

Just wondering what type of times are out there.

Just for comparison, when I do an Ironman or train for one, I try to get my 112 in about 5h 15 to 20 minutes. If I try for faster, my legs will be torched for the run. I know you young studs can brag about your sub fives but it would blast me for the run.
