Roger - you are quite right - there was a horse that appeared lame in one of the coloured classes that was well placed. However, I do hope that you will not taint ALL show horses with the brush of being overweight and lame. We strive to ensure that our own show horses are fit (they all go to the park regularly and work properly for 2 hours on the tracks), and definitely not fat.
Our horses go out in the field at least 4 times a week (more, if this is what they prefer - less if they would rather be in the middle of the action), they have a 3 month holiday where they can just be "horses" after HOYS, and during the showing season do lots of hacking, jumping and socialising with other horses and very little schooling or just standing in a stable. I think you would be able to see the enjoyment that our horses display in the ring and would not associate that with steroid abuse (disgusting), doping (unnecessary), overweight (again, unnecessary)
