Thank you for posting the link. If Mark Johnston, who trains more 2YO winners in the world each year, says they are at their heaviest at age two, I have to believe it's true.

There is a fantastic young sprinter in Hong Kong named Aethero who weighs 1254 pounds of 570 kilograms. At 17 hands, it's amazing how fast he is. But, it has to be a challenge to keep him sound.
