I think I've scared a few people off ...
There was one guy who thought it would be no problem at all to ride a century with me ... in Manitoba ... in November ... having ridden his longest distance of 100 km many years earlier. I questioned whether he was really prepared for that sort of ride, but he was one of these cycling advocate types who commuted a few km to work every day, and thought he could handle it. He finished, but I'm not sure he knew his name anymore when he rolled in at the end. And to my knowledge he never cycled that sort of distance again.
