I've seen plenty of guys say they're clydes and then say they're like 210 or whatever. Yes, registering for a triathlon at 210 you'll be in the clydesdale class, so it's no lie, but I just want to shake my head and say "*****, please!"
I brought that video up and when I realized it was just a tall guy who's genuinely heavier than the typical beanpole cyclist, but still looked perfectly normally sized, I just closed the browser again. Move along, this isn't the clydesdale you're looking for...
