I'm wondering about the weight issue too.

I also wonder about the preparation of the horses. Marathon runners are, in general, fantastically and specifically well trained for their sport. Are the horses involved specifically trained for endurance racing or just generally fit horses? Are they elite endurance racers? If the horses are specifically trained, does the fact that most equine endurance races are 50 or 100 miles effect the training of the horses?
