I used to train thoroughbreds at the race track, so have seen all aspects. To me, pictures of the race itself all look the same unless you are getting a really spectacular image of a well-known racer, eg. a champion. Then it has some meaning besides being a pretty sight. Some of the things I would love to have taken pictures of: dark horse getting a soapy bath on a cool morning - steam rising; horse training early morning when there are clouds low on the ground and all you see are the rider and the horse's head and neck (saw this in New Orleans). There are many others, but won't try to list all!
Anyone who wants photos of horses in motion ought to go to the track in the early morning. Saratoga has a breakfast program, and you can watch the horses train. They also give a bus tour of the barn area. Setting up a tripod or monopod during the races can be tricky because of the crowds, but in the AM it works well.
Horses in motion are tricky for me, since I am relatively new at this. I went to the horse show here in Dorset, Vermont last summer and tried to get some decent photos. Tried using bursts and different settings. Got some nice ones but many more that don't really impress. Lots of heads and/or legs cut off, many almost cut.
The bright sand also made the exposure tricky. This is my first DSLR, just got it last February, so in July I was having trouble with all of that. Still do, now with snow, but have improved!!!
