PHOTO: Those Quads Are Not Normal, Sir

Athletes at the Olympics have lots of downtime, and are usually left to their own means of entertainment when not competing. If you're a cyclist, apparently that means an impromptu "quad-off." The photo of it, after the jump, is mildly NSFW, and is definitely nuts.

GOOD LORD.

The picture was tweeted by Greg Henderson, a cyclist from New Zealand. Germany's André Greipel, who finished 27th in Saturday's Road Race, is on the left. I have no idea who the Hulk is on the right, but I am going to assume he is a track cyclist. Good luck trying to beat ... those.
